Fun and Interesting Chemistry Facts and Trivia

Chemistry is a fascinating science full of unusual trivia. Some of the  most fun and most  interesting chemistry facts include: The only solid elements that assume liquid form ​at room temperature are bromine and mercury. However, you can melt gallium by holding a lump in the warmth of your hand.Unlike many substances, water expands as it freezes. An ice cube takes up about 9% more volume than the water used to make it.If you pour a handful of salt into a full glass of water, the water level will actually go down rather than overflowing the glass.Similarly, if you mix half a liter of alcohol and half a liter of water, the total volume of the liquid will be less than one liter.There is about 0.5 pound or 250 grams of salt (NaCl) in the average adult human body.A pure element takes many forms. For example, diamond and graphite both are forms of pure carbon.Many radioactive elements actually glow in the dark.The chemical name for water (H2O) is dihydrogen monoxide.The only letter not appearing on the periodic table is J.Lightning strikes produce O3, which is ozone, and strengthen the ozone layer of the at mosphere.The only two non-silvery metals are gold and copper.Although oxygen gas is colorless, the liquid and solid forms of oxygen are blue.The human body contains enough carbon to provide lead (which is really graphite) for 9,000 pencils.Hydrogen is the most abundant element in the universe, while oxygen is the most abundant element in the Earths atmosphere, crust, and oceans (about 49.5%).The rarest naturally occurring element in the Earths crust may be astatine. The entire crust appears to contain about 28 grams of the element.Hydrofluoric acid is so corrosive that it will dissolve glass. Although it is corrosive, hydrofluoric acid is considered to be a weak acid.One bucket full of water contains more atoms than there are buckets of water in the Atlantic ocean.Approximately 20% of the oxygen in the atmosphere was produced by the Amazon rainforest.Helium balloons float because helium is lighter than air.Bee stings are acidic, while wasp stings are alkaline.Hot peppers get their h eat from a molecule called capsaicin. While the molecule acts as an irritant to mammals, including humans, birds lack the receptor responsible for the effect and are immune to the burning sensation from exposure.Its possible to die from drinking too much water.Dry ice is the solid form of carbon dioxide (CO2).Liquid air has a bluish tint, similar to water.You cant freeze helium simply by cooling it to absolute zero. It will freeze if you apply extremely intense pressure.By the time you feel thirsty, youve already lost about 1% of your bodys water.Mars is red because its surface contains a lot of iron oxide or rust.Sometimes, hot water freezes more quickly than cold water. A high school student documented the effect, which bears his name (the Mpemba effect).

How Incarceration Fails As A Method Of Illicit Drug Control

In 2014, approximately 13 million people are injecting drugs worldwide, which is an alarming 0.3% of the entire adult population (UNAIDS, 2014). Injecting drugs often results in increased negative health consequences and may lead to the transmission of blood-borne viruses such as HIV. As of now, about 1.7 million, or 13% of the injected drug users are living with HIV (UNAIDS, 2014). Though featured in nearly every country, injected drug use is still treated as a crime and lead easily to incarceration (UNAIDS, 2014). This essay seeks to examine how incarceration fails as a method of illicit drug control and puts an already at-risk group in further peril. About 56% to 90% of injected drug users will be incarcerated at some point in their lives worldwide. Imprisonment, however, will not necessarily eliminate an individual’s access to illicit drugs. If anything, illicit drugs may be cheaper inside of the jails than outside (Pisani, 2008). Some prisoners even inject drugs for the f irst time in jails, thus potentially initiating dependence under the most unfavorable circumstances. While drugs may be cheaper, the clean needles required to inject them safely is a lot less affordable in comparison (Pisani, 2008). According to Elizabeth Pisani in her book, The Wisdom of Whores, clean needles cost three dollars apiece while a hit of heroin cost fifty cents less (2008). Due to this, the same needle usually passes around and if one prisoner was infected with HIV, the virus will soon beShow MoreRelatedEssay on Americas War on Drugs5842 Words   |  24 PagesNixon initiated the War on Drugs when American soldiers were coming home from the Vietnam War addicted to heroin.

Learning in English Essay Example For Students

Learning in English Essay The activity consists of the pupils watching the report and then producing a written account, using their imagination to devise their own interpretation. One of the reasons behind the use of the French report is to include the EAL pupil in a positive way. To achieve this I will ask her to give an account to the whole class of the true facts and information found on the video. Thus displaying the importance of communication and therefore encouraging her to embrace her own individuality. In turn I hope this will help the rest of the class to recognise and respect the difficulties that EAL pupils can face in everyday learning. Displaying the video on the interactive whiteboard in this way will assist me with incorporating information communication technology (ICT) into my literacy teaching. ICT can help teachers, when used effectively to improve their teaching. In this case, I will use ICT effectively with a large display on the board to show the class a visual, interactive video. They will also have the opportunity to use ICT during lesson five when performing their own news reports to the class. The pupils will be able to use overhead projectors, audio sound effects and power point presentations to assist them with their work. Teachers must always consider how they can produce lessons that are effective as possible. When planning my unit of work I considered the lessons with and without the use of ICT and found that I could in fact make these activities more effective with the inclusion of these resources. (Sadler, 1994) I understand the importance of differentiating work to suit the needs of all children within my class. Not only must I develop strategies to progress the EAL pupil, but I must also help children of different abilities. I will differentiate the activities by providing support sheets for children of a lower ability. As with the EAL pupil, prompt sheets and planning guidance, such as checklists will be given to pupils of a lower ability to assist them with their written work. The use of group work also gives the pupils of a higher ability the opportunity to guide and help pupils who may be struggling. My class teacher reassured me that pupils of a lower ability need encouragement and praise to help increase their confidence, therefore I have planned to give children the opportunity to share their achievements with the class during the plenary of each lesson. During this time I will highlight the strengths of the pupils individual work, giving them confidence in their ability, thus encouraging them to reproduce this effort in future lessons. My unit of work provides great opportunity for assessment. This is mandatory for all teachers, as they must have a sound knowledge of the levels their pupils are achieving ensuring that they are delivering lessons that challenge and progress their pupils. It is important that pupils are working at an appropriate level whereby they do not find their work too easy, as this could cause a plateau in their learning, just as importantly the work must not be too difficult as they can feel threatened by the challenge. To achieve this, teachers must assess their pupils, to understand the level they are working at, to show what they aim to achieve. I plan to use continuous assessment, both formal and informal. Observation and questioning will assist me in gaining an understanding of the pupils ideas and developments, and marking their written work will help with individually levelling the pupils. The purpose of the assessment process is to make explicit childrens achievements, celebrate their achievements with them, then help them to move forward to the next goal (Sainsbury, 1996. P. 9) With this in mind, I plan to incorporated peer, self and teacher assessment into my unit of work, helping the children to track their own achievements, and take pride in their personal growth. I believe that I have justified the key aspects of my unit of work, through designing a plan that is enjoyable and relevant for all pupils. .ude18e3bd89eea3f110ec637a0159eb0d , .ude18e3bd89eea3f110ec637a0159eb0d .postImageUrl , .ude18e3bd89eea3f110ec637a0159eb0d .centered-text-area { min-height: 80px; position: relative; } .ude18e3bd89eea3f110ec637a0159eb0d , .ude18e3bd89eea3f110ec637a0159eb0d:hover , .ude18e3bd89eea3f110ec637a0159eb0d:visited , .ude18e3bd89eea3f110ec637a0159eb0d:active { border:0!important; } .ude18e3bd89eea3f110ec637a0159eb0d .clearfix:after { content: ""; display: table; clear: both; } .ude18e3bd89eea3f110ec637a0159eb0d { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ude18e3bd89eea3f110ec637a0159eb0d:active , .ude18e3bd89eea3f110ec637a0159eb0d:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ude18e3bd89eea3f110ec637a0159eb0d .centered-text-area { width: 100%; position: relative ; } .ude18e3bd89eea3f110ec637a0159eb0d .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ude18e3bd89eea3f110ec637a0159eb0d .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ude18e3bd89eea3f110ec637a0159eb0d .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ude18e3bd89eea3f110ec637a0159eb0d:hover .ctaButton { background-color: #34495E!important; } .ude18e3bd89eea3f110ec637a0159eb0d .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ude18e3bd89eea3f110ec637a0159eb0d .ude18e3bd89eea3f110ec637a0159eb0d-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ude18e3bd89eea3f110ec637a0159eb0d:after { content: ""; display: block; clear: both; } READ: At the start, Macbeth and Lady Macbeth are 'kind hostess', but by the end they are 'this dead butcher and his fiend-like queen' EssayI understand that it is mandatory for teachers to Decide what element to teach by considering what the children will respond to, the need of their age group, and the needs of individuals in the class, (Joyce, M, 1973, page 56). Discussion with the class teacher has enabled me to plan lessons that will suit the specific needs and interests of all the pupils within the class, helping me to deliver lessons that are personalised and subsequently very effective. All of the lessons are of great educational value and help the children develop their skills and understanding in Literacy as well as in other subjects. Whilst planning, I took great care in including differentiation, assessment, ICT and progression allowing me also to develop my own confidence and professionalism as a teacher. I am looking forward to having opportunity to teach my unit of work in the near future. References Arthur, J Grainger, T, Wray, D. (2006) Learning to Teach in the Primary School. Oxon: Routledge.

Case Study Of Tom Shareholder Of The ABC Ltd †Free Samples

Question: Discuss about the Case Study Of Tom Shareholder Of The ABC Ltd. Answer: In the given case study, Tom was a minor shareholder of the ABC Ltd. The directors of the company had sold the assets of the company to purchase an island resort in their own names. Therefore, the directors are said to be the controlling shareholders of the company and hence, they will have more rights on the property compared to a minority shareholder[1]. Tom was made aware of these activities at a general meeting and soon after he wanted to take an action against the directors of the company. As per the Company Law, the directors will be held liable if they take such actions by not disclosing it to the existing shareholders of the company. Being a minor shareholder, Tom can claim for his amount of shares that he had invested in the ABC Ltd. As per the guiding rules on Principle 2, individual directors has direct control and right over the company of ABC Ltd[2]. but it is also their responsibility to inform every shareholder of the company about the activities. Therefore, Tom can in itiate an action against the directors. As seen in this case study, Flywell Ltd was the owner of an Australian airline. The Flywell Ltd. wished to persuade each investor to invest $10,000 with the company. The company had focused to raise the funds between $9 million and $11 million in new funds. Therefore, a company can raise its fund with the help of five primary methods that are generally used by the corporations[3]. It can issue bonds, put a sale on the common stock, can issue preferred stock, borrow from finance inventories and can put the profits on use. Proportional granting of ownership in the firm is given to the investors in exchange of money. Corporations raise money by this popular method. Therefore, the Flywell Ltd can fund raise the obligations by these primary methods under the Corporations Act. The Board of Directors of Flywell Ltd can purchase extra plains by raising the funds since the company does not have sufficient capital fund[4]. The advice, which the Flywell Ltd. should be given, is that it should u tilize the primary sources for raising the funds. References: Bgioi, Adrian Doru, and Cristina Elena Dumitru.
