Question

The free the freezing point of a substance is same as the melting point of its solid state justify the statement with the suitable answer example

Answer 1

The melting point of a substance is the temperature at which the substance changes from solid to liquid at atmospheric pressure. 

At the melting point, the solid and liquid phase exists in equilibrium. 

When considered as the temperature of the reverse change from liquid to solid, it is referred to as the freezing point. 

Hence the freezing point of liquid is same as the melting point of it's solid state.

For example, the melting point of ice and the freezing point of water is same, which is 0 C at atmospheric pressure.
