Generating Electricity
Presentation - 10 pages - Physics
The blade of a turbine is tilted an angle. Movement of the air is channeled creating low and high pressures on the blade that force it to move. The blade is connected to a shaft which in turn is connected to an electrical generator. The mechanical energy of the turning blades is changed into...
Development in LSD Synthesis
Essay - 3 pages - Physics
LSD, the common abbreviation for Lysergic Acid Diethylamide-25, often termed acid in the streets, is one of the most potent hallucinogenic substances known to man. The chemical was actually synthesized for the first time in 1938 by a German scientist named Albert Hoffman. However, in...
Ka and Buffer Titrations
Case study - 2 pages - Physics
As living things, we are highly sensitive to changes in our environment; this doesn't only mean changes outside our body, but changes from within also. For the cells in our bodies to function properly a certain temperature and pH has to be maintained. Even a slight change in pH inside our bodies...
Experiment: Mole Ratios, Limiting and Excess Reactants and Precent Yield
Case study - 4 pages - Physics
The purpose of this lab is as follows: To use mole ratios to predict the amount of precipitate formed, to use mole ratios to study the effect of reactant molarity on the yield of product, to use mole ratios to study limiting and excess reactants, and to design an experiment which achieves the...
Chemical Changes
Case study - 6 pages - Physics
The purpose of this lab was to find out the indications of chemical changes and reactions when mixing two different substances, which are listed specifically in the Observations section. The purpose is also to find out how a percent by mass solution is made up. The data and observations that is...
Ferromagnetism and the Curie-Weiss Law
Course material - 3 pages - Physics
In "Ferromagnetism and the Curie-Weiss Law" the author will start by giving a more complete derivation of the Curie-Weiss law, which might make a few points clearer. Then he will try to address some of your questions more directly. The author hopes that the derivation itself will make things...
