APES AP Exam Review (2023/2024) 100% Pass First Law of Thermodynamics energy is neither created nor destroyed, may be converted from one form to another. Second Law of Thermodynamics when energy is changed from one form to another, some useful energy is degraded into lower quality energy (usually heat). Energy the ability to do work. Units of energy: joules, calories, kilocalories, British thermal units (BTUs), Kilowatt-hours (kWh) Power the rate of doing work (work/time). Units of power: wat...
