the energy stored in the chemical bonds between atoms. chemical energy

a change in which energy is absorbed. endothermic change

the total energy of all of the particles in an object. thermal energy

the fact that matter is neither created nor destroyed in any physical or chemical change. law of conservation of mass.

alters the form or appearance of matter but does not turn any substance in the matter into another substance. physical change

a change in matter that produces one or more new substances. chemical change.
