Living In Space: Energy
Space is filled with radiant energy and beyond earth's atmosphere this energy flow more steadily and more intensely from the sun than that which penetrates to the surface of the Earth.

How Technology Effects Modern America - US Wage Trends
The microeconomic picture of the U.S. has changed immensely since 1973, and the trends are proving to be consistently downward for the nation's high school graduates and high school drop-outs.

Representative Gases & Properties of Gases
1. State the five assumptions of the Kinetic-Molecular Theory of gases.
a) Gases consist of large numbers of tiny particles. These particles, usually molecules or atoms, typically occupy a volume about 1000 times larger than occupied by the same number of particles in the liquid or solid state.
