Would you state the law of conservation of energy and explain how they apply to changes of state?
Answer:
Law of Conservation of Energy: In a closed system, energy is conserved. In changes of state the energy is absorbed by changing a liquid to a gas or solid. This happens wiothout a change in temperature. The energy of the matter has increased without changing it temperature but it has changed its energy content in more or less kinetic energy as gas or solid from liquid.
