Thermochemistry is the study of heat change in chemical reactions.
Energy is the capacity to do work.
Units of Energy
Calorie (cal) is the amount of energy required to raise 1 gram of water by 1 degree Celsius
Joule (J)
1 cal = 4.184 joules
Kilocalorie (Kcal)
1000 cal = 1Kcal = 4184 J
Kilojoule (KJ)
1 KJ = 1000 J
