A solid material is supplied heat at a constant rate. The temperature of material is changing with heat input as shown in the figure. What does the slope of DE represent ?

A

latent heat of liquid

B

latent heat of vapour

C

heat capacity of vapour

D

inverse of heat capacity of vapour

Text Solution

Verified by Experts

The correct Answer is:
D
`DeltaQ = mcDeltaT`
Slope of inclined line `(DeltaQ)/(DeltaT) = 1/(mc)` = 1/(Thermal capacity)

A solid material is supplied with heat at a constant rate. The temperature of the material is changing with heat input as shown (i) AB: change of state from solid to liquid. CD: change of state from liquid to vapour (ii) When CD=2AB , i.e., latent heat of vapourization is twice the latent heat of fusion of the substance. (iii) The reciprocal of slope of DE represents the heat capacity of vapour state of substance . (iv) If slope of OAgt slope of BC, i.e., specific heat of liquid state is greater than specific heat that of solid state.
