Question

Assertion: Burns from Boiling water is more serious than steam at same temperature. Reason: Water has higher Latent heat of fusion as compared to latent heat of vaporisation.

A graph between the temperature T and Pressure P of the substance is called a Phase Diagram. The following figure shows the phase diagram of water and carbon dioxide. Such a phase diagram divides the P - T plane into three regions - solid region, vapour region and liquid region
