Answer:

Yes, energy can either be absorbed or given off when matter changes state, while the temperature of the system remains constant

Explanation:

Endothermic changes are changes in which energy is absorbed, some possible state changes that demonstrate endothermic changes are: ice to water (melting), water to steam (boiling), ice to steam (sublimation)

Exothermic changes are changes in which energy is given off, some possible state changes that demonstrate exothermic changes are: steam to water (condensation), water to ice (freezing), steam to ice (deposition)
