Why Save Electricity? With the rising costs and shrinking economy more and more people are acting responsible and seacrhing for reasonable ways to save electricity. The other reason apart from these are that saving electricty will bring down your electicity bills‚ save you money and decrease pollution. Although many people have shifted to renewable sources such as solar power‚ there are other electricty saving tips too which will help you to conserve power. Electricity Saving At Home Replace

BIOCHEMICAL IMPORTANCE OF WATER Of all the simple chemicals that are found in abundance on Earth‚ only water is liquid under normal pressure and temperature. When life first appeared on planet Earth‚ water has played an important role in creating the first organic compounds. The organic compounds later‚ formed the first prokaryotic organisms. Life began‚ as the modern theories support‚ in water and developed for three billion years in it before spreading on land. It is no coincidence that the

Class 4 – Flammable Solids Division 4.1 – Flammable Solids are: • Wetted explosives that are Class 1 explosives when dry‚ that are sufficiently wetted to suppress explosive properties. • Self-reactive materials that are thermally unstable and can undergo strong exothermic decomposition even in the absence of oxygen. Readily combustible solids that can cause fire through friction‚ such as matches. Powdered‚ granular or pasty materials must be classified as Division 4.1 when the time of burning of

AMERICAN INTERCONTINENTAL UNIVERSITY SUBJECT: Municipal Solid Waste Descriptions and Problems ABSTRACT: The Municipal Solid Waste is based in 4 main components that are recycling‚ composting‚ landfilling and waste-to-energy that is mainly done by burning the waste. This is known as materials of no longer being of value and is thrown out for disposal. Waste is handled and separated into different containers which are divided into solids‚ plastics and paper mainly. There are different types of

Surface Tension Properties of Liquids Introduction The purpose of this experiment is to measure and record the surface tension of water and other aqueous solutions using capillary rise method techniques and practicing lab safety. In this laboratory the surface tension of water depends on the concentration of the following solutes; NaCl‚ acetone‚ and sodium dodecyl sulfate (SDS). Intermolecular interactions as well as other phases (solid‚ or air) make a liquid exist. The data collected will show
