requested information about thermo-chromic material and how can be benefits to our company. Before I give description about above material I would like to thank you for giving me opportunity and give me enough time and source to search information about this new material. Thermochromism is the reversible change in the color of a compound when it is heated or cooled. Systematically investigated thermochromism was in 1971 at first time. The following 4 materials are used as thermochromism (1) Organic

Lab #2 – Separation of a Mixture of Solids Abstract The mixed solution contained benzoic acid‚ iron‚ table salt‚ and sand. When separated using water‚ fuel‚ or a magnet‚ their characteristics and properties changed. The mass of the entire mixed solids was 6.6 grams. When the magnet was used‚ the iron was immediately picked up. The mass for that was 1.7 grams. The table salt was 1.2 grams. Benzoic acid mass was 0.8 grams and the sand was 1.4 grams after being separated. Introduction The objective

LS Separation of Mixtures and Solids Purpose: To become familiar with the separation of mixtures of solids Hypothesis: I will be able to separate the materials using a variety of different methods. First‚ separate the iron fillings using a magnet. Second‚ I will put the rest of the solution into water and separate the insoluble sand from the soluble salt and benzoic acid. Third‚ I will filter out the benzoic acid when crystalized. Lastly‚ I will evaporate the water away leaving crystallized

types of solid waste. To handle it well‚ we used to categorize and separate the type of waste. In waste water treatment‚ we simply separate the pollution as municipal waste (more polluted) and runoff(less polluted). But in solid waste‚ we define it as three types of waste that is more detail then water. They are Municipal Solid Waste (MSW)‚ Construction Waste and Special Waste. We defined these wastes by their properties. The figure shows that we have successfully reduce the total solid waste

Solid Waste Management in Mumbai Mumbai has a coastal stretch of 603 sq km. Geographically‚ the city of Mumbai can be divided into three sections‚ namely‚ the island city (or main city)‚ the western suburbs and the eastern suburbs. These are also known for administrative purposes as Division I‚ Division II and Division III‚ respectively. The total population of the city amounts to nearly 13million that is increasing on a daily basis. Such a huge habitat obviously generates a huge amount of waste

Lab 3 – Separation of a Mixture of Solids Cathy Lab Partners: Chelsea Brooke Sept 4‚ 2012 Chemistry 131A Dr. Vicki H Audia Pelab Questions: Proposed procedure for separation of a mixture: Use physical properties of the 4 substances to separate. 1. Remove iron with magnet 2. Add water to the mixture to melt the benzoic acid and NaCl then filter out sand. 3. Chill the solution and scoop the acid out leaving a salt solution. 4. Boil water away leaving salt. Purpose: The

FROZEN ROCK-SOLID At General Motors of Canada Ltd.‚ Nick Vanderstoop is in charge of implementing a system that he created to prevent the “erosion of knowledge”. He loves to scare the daylights out of GM executives and managers by telling them a true story about the company. The story goes something like this: Several years ago a worker at the head office of General Motors Canada Ltd. In Oshawa retired. Among the many tasks that were performed by him‚ one was particularly important. Every fall he
