Q.

A solid body is supplied heat at a constant rate. The temperature of the body is changing with the heat input as shown in the diagram.
a) The horizontal region CD shows the change of state, solid to liquid.
b) The slope DE gives the inverse of water equivalent of the substance in the gaseous state.
c) If CD = 2.AB then the heat of fusion of the substance is twice the latent heat of condensation.
d) The fact that the slope of OA is greater than the slope of BC shows that the specific heat of the substance in the solid phase is smaller than that in the liquid phase.
