Plot temperature variation of heat capacity for first order and second order phase transitions.

Answer:

(a)

(b)

a) First order phase transition.

The infinite value of heat capacity at the first order phase transition corresponds to the fact that a nonzero amount of heat produces n change in the temperature as one phase is converted to the other.

b) Second order phase transition.

Heat capacity at second order phase transition doesn't become infinite, although it has discontinuity in the figure.
