Question

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 reasonable approximation

Answer 1

(i) in 0 - 100 K C increase, so R increases but not linearly

(ii) ΔQ = mCΔT as C is more in (400 K - 500 K) then (0 - 100 K) so heat is increasing

(iii) C remains constant so there no change in R from (400 K - 500 K)

(iv) C is increases so R increases in range(200 K - 300K)
