Detailed explanation-1: -Changing states of matter occur when matter loses or absorbs energy. When a substance absorbs energy; the atoms and molecules move more rapidly and this increased kinetic energy pushes particles far enough that they change form. This energy is usually heat or thermal energy.
Detailed explanation-2: -during a change of state, but the energy of a substance does change. Some changes of state require energy. Changes of state that require energy are melting, evaporation, and sublimation. Energy is released in some changes of state.
Detailed explanation-3: -Thus any transition from a more ordered to a less ordered state (solid to liquid, liquid to gas, or solid to gas) requires an input of energy; it is endothermic. Conversely, any transition from a less ordered to a more ordered state (liquid to solid, gas to liquid, or gas to solid) releases energy; it is exothermic.
Detailed explanation-4: -One change of state happens when you add energy to the substance. This change of state is called melting. By adding energy to the molecules in a solid the molecules begin to move quicker and can break away from the other molecules.
Detailed explanation-5: -Energy is consumed to change a substance from solid to liquid to gas. Energy is released to change a substance from gas to liquid to solid.
