Heat of Fusion

The video tutorial explains the concept of heat of fusion, which is the energy required to change a solid to a liquid at its melting point, and vice versa. It highlights that this energy only accounts for the phase change without affecting temperature. The tutorial provides examples, such as the heat of fusion for water, and explains how it can be calculated in joules per gram or kilojoules per mole. It also discusses the heat of fusion for other substances like paraffin wax and zinc. The video concludes with the importance of understanding heat of fusion in scientific applications, such as manufacturing silicone chips.
