50 miles per gallon. The efficiency of Internal Combustion Engines used for this purpose is very low‚ about 25%. The heat generated during the combustion of fuel is converted into work to drive the car is wasted to the atmosphere‚ as anti-freeze(Ethylene Glycol) is used to cool the engine and circulated through a radiator which transfers the heat to the atmosphere. The heat generated by combustion of fuel such as gasoline or diesel is converted into the work because of the pressure created by the

repeat) unit is ÀCH2ÀCH2À and n represents the chain length of the polymer. Polymers are obtained through the chemical reaction of small molecular compounds called monomers. For example‚ polyethylene in Eq. (1.1.1) is formed from the monomer ethylene. In order to form polymers‚ monomers either have reactive functional groups or double (or triple) bonds whose reaction provides the necessary linkages between repeat units. Polymeric materials usually have high strength‚ possess a glass transition

For my science fair project‚ I figured out what solvent would work best to erase permanent marker. The solvents I tested were: lemon juice‚ vinegar‚ water‚ and rubbing alcohol. I tried each of these solvents on a permanent marker line on plastic‚ paper‚ fabric‚ and wood. In this research paper‚ I will be talking about what a permanent marker is‚ how they are made‚ why they work so well‚ what rubbing alcohol is and its common uses‚ what vinegar is and its common uses‚ what water is and why water is

successful‚ millions of gallons of water are needed. The need for this much water is depleting our fresh water supply. Up to six hundred different chemicals are used in fracking‚ most of which are very toxic‚ including uranium‚ mercury‚ formaldehyde and ethylene. A lot of this now toxic water stays underground and could potentially contaminate a necessary resource‚ our water supply. Some of the chemicals used have been known to cause infertility‚ autism‚ ADHD‚ diabetes and thyroid disorders. (“Fracking
