When something changes phase from solid to liquid, or from liquid to gas, it takes energy to break the intermolecular interactions. These interactions between the water molecules are what make it solid. When you have ice, these interactions are strongest, which is why ice is hard.
Heat and motion are both forms of energy. The. energy of motion can be converted into the energy of heat. Heat can cause a substance to change its temperature or to change its. state from a solid to a liquid or a liquid to a gasâor even from a solid to a gas. In this chapter we look at interactions that involve changes in temperature. and changes in state. Changes in temperature are described in terms of the.
