The figure below shows the variation of specific heat capacity (C) of a solid as a function of temperature (T). The temperature is increased continuously from 0 to 500 K at a constant rate. Ignoring any volume change, the following statement(s) is (are) correct to a reasonable approximation.
Select ALL correct options:
A
the rate at which heat is absorbed in the range $0-100 \mathrm{~K}$ varies linearly with temperature T .
B
heat absorbed in increasing the temperature from $0-100 \mathrm{~K}$ is less than the heat required for increasing the temperature from $400-500 \mathrm{~K}$.
C
there is no change in the rate of heat absorbtion in the range $400-500 \mathrm{~K}$.
D
the rate of heat absorption increases in the range $200-300 \mathrm{~K}$.
