For example if ice (solid) is heated it changes its state to water (liquid) and if this water is further heated it becomes water vapour (gas). Conversely when a gas loses heat energy it changes into a liquid and on further cooling it freezes into a solid.

Answer 2

Answer:

When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).
