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 at a constant rate. Ignoring any volume change, the following statement(s) is (are) correct to a reasonable approximation.
Match the following statements related to the variation of specific heat capacity (C) with temperature (T):

Statements Explanation

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

(B) Heat absorbed in increasing the temperature from the range _ is less than the heat required for increasing the temperature from 400 - 500K. (Q) 400 - 500K

(C) There is no change in the rate of heat absorption in the range (R) 300-400 K.

(D) The rate of heat absorption increases in the range (S) 200 - 300K.

Question

Question

Answer 1

Explanation:

Option (A) is correct because the graph between appears to be a straight line up to a reasonable approximation.

Option (B) is correct because the area under the curve in the temperature range is less than in range .

Option (C) is correct because the graph of C versus T is constant in the temperature range .

Option (D) is correct because in the temperature range specific heat capacity increases with temperature.

∴ All options are correct.
