Matter and its Construction: Heat of Fusion and Vaporization

The video tutorial explains the concepts of heat of fusion and heat of vaporization. Heat of fusion is the energy required to change a solid to a liquid at its melting point without changing temperature or pressure. An example is melting ice, which remains at 0°C during the process. Heat of vaporization is the energy needed to convert a liquid to a gas at its boiling point, such as water boiling at 100°C. The video highlights that these heat values differ for various substances.
