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.

1. The rate at which heat is absorbed in the range
   0-100 K varies linearly with temperature T.
2. Heat absorbed in increasing the temperature from 0-100 K is less than the heat required for increasing the temperature from 400-500 K.
3. There is no change in the rate of heat absorption in the range 400-500 K.
4. The rate of heat absorption increases in the range 200-300 K.
