Matter can change from one state to another when thermal energy is absorbed or released. A great example is Ice having its state changed to the liquid that is WATER. When ice is heated, it absorbs thermal energy and its temperature rises. At some point, the temperature stops rising and the ice begins to change to water, a liquid. As we all know, The change from the solid state to the liquid state is called melting.
