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

q = mCT dq dt = mc dT dt R = rate of absorption of heat = dq dt ∝ C (i) in 0 - 100K The graph between ( 0 - 100K ) appears to be a straight line upto a reasonable approximation. (ii) Δ q = mC Δ T as C is more in ( 400 - 500K ) then ( 0 - 100K ) so heat is increasing. (iii) C remains constant so there no change in R from ( 400 - 500K ) (iv) C is increases so R is increases in range ( 200 - 300K )
