Q .     The figure 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.

JEE 2013 Mains
A

The rate at which heat is absorbed in the range 0-100 K varies linearly with temperature T.

B

Heat absorbed in increasing the temperature from 0-100 K is less than the heat required for increasing the temperature from 400 – 500 K.

C

There is no change in the rate of heat absorption in range 400 – 500 K.

D

The rate of heat absorption increases in the range 200 – 300 K.
