relationships between chemical reactions and energy changes involving heat
energy
capacity to do work or produce heat, needed to oppose natural attractions
law of conservation of energy
energy can be converted from one form to another but cannot be created or destroyed
(first law of thermodynamics)
kinetic energy
energy of motion, increases as speed and mass increases
potential energy
energy an object possesses by virtue of its position
joule
energy SI (1 kg*m^2/s^2)
calorie
4.184 J =
Calorie
