PHASES OF MATTER; PHASE CHANGES; MATTER AND ENERGY

What does the law of conservation of matter and energy say?

• that matter changes phase when it absorbs thermal or heat energy

• that all matter melts when heated

• that matter and energy cannot be created or destroyed, but just transformed from one form into another

• that energy causes motion in matter
