Read the given paragraph on the process of melting. Identify the incorrect parts of the process.
Melting or fusion is a chemical process that involves the change of state from gaseous to liquid state on the liberation of heat. During the process of melting, there is a sharp change in the temperature until the process is complete. The temperature at which solid melts or changes into its gaseous state is known as the freezing point. During the melting of a solid, the heat released by the body does not raise its temperature. For example, the melting point of ice is 100°C, so the temperature of ice remains steady until all the ice melts.
