this experiment was to obtain some experimental measurement of Vapor Liquid Equilibrium for the Ethanol – Water system to verify the literature data. For this the Ethanol – Water system was heated to a certain temperature which is called the equilibrium temperature at atmospheric pressure and equilibrium temperature and compositions of vapor and liquid were measured. At the equilibrium temperature the samples of both vapor and liquid were taken in two different test-tube and the refractive index of

The temperature at which electrical resistance is zero is called the critical temperature (Tc) and varies with the individual material. For practical purposes‚ critical temperatures are achieved by cooling materials with either liquid helium or liquid nitrogen. The following table shows the critical temperatures of various superconductors:

I believe that products similar to this have just taken advantage of a sudden increase in popularity and demand for deer antler spray and are covered by the Dietary Supplement Health and Education Act of 1994 to sell their product without backing up their claim. In order to prove my hypothesis‚ DVX Pro Liquid would need to be

class 9. Introduction Solid waste is an byproduct of human activities which tends to increase with rapid urbanization‚ improved living standards and changing consumption patterns. Management of increasing amounts of solid waste has become a major challenge in many cities in developing countries. If solid waste is properly used‚ it can be a valuable resource‚ but if it is not effectively managed‚ it can result in serious adverse impacts on environment and public health. Solid waste management is therefore

between the South China Sea and the Philippine Sea. With a rapidly growing population and lack of adequate disposal sites‚ solid waste has become a major problem for most medium to large-size cities. When Philippine President Gloria Macapagal Arroyo took office in January‚ 2001‚ the first act she signed into law dealt with solid waste management. In recent years‚ inadequate solid waste management systems have posed serious health risks particularly in densely populated areas. In Manila‚ for example

Electricity can be produced by burning "municipal solid waste" (MSW) as a fuel. MSW power plants‚ also called waste to energy (WTE) plants‚ are designed to dispose of MSW and to produce electricity as a byproduct of the incinerator operation. The term MSW describes the stream of solid waste ("trash" or "garbage") generated by households and apartments‚ commercial establishments‚ industries and institutions. MSW consists of everyday items such as product packaging‚ grass clippings‚ furniture‚ clothing

The Five Platonic Solids The five platonic solids are the tetrahedron‚ cube‚ octahedron‚ dodecahedron‚ and a icosahedron. They are named for the greek philosopher Plato. Plato wrote about them in the Timaeus (c.360 B.C.) in which he paired each of the four classical elements earth‚ air‚ water‚ and fire with a regular solid. Earth was paired with the cube‚ air with the octahedron‚ water with the icosahedron‚ and fire with the tetrahedron. The fifth Platonic solid‚ the dodecahedron‚ Plato says that

Solid Wastes Management BASURA‚ GARBAGE‚ GOMI‚ ORDURES‚ AFVAL‚ SPAZZATURA— whatever people call it‚ solid waste is a problem that must be properly managed. While it is generally understood that proper waste management helps protect human health and the environment and preserve natural resources‚ many do not realize that solid waste also impacts climate change. The manufacture‚ distribution‚ and use of products—as well as the disposal of the resulting waste—all result in emissions of atmospheric
