First Law of Thermodynamics correct answers energy is neither created nor destroyed, may be converted from one form to another. Second Law of Thermodynamics correct answers when energy is changed from one form to another, some useful energy is degraded into lower quality energy (usually heat). Energy correct answers the ability to do work. Units of energy: joules, calories, kilocalories, British thermal units (BTUs), Kilowatt-hours (kWh) Power correct answers the rate of doing work (wor...
