Answer:
Option B,C,D
Explanation:
Q=mCT
dQdt=mcdTdt
R= rate of absortion of heat = dQdt∝C
(i) in 0-100K
C increase, so R increase but not linearly
(ii) △Q−mC△T as C is more in (400 K-500K) then
(0-100K) so heat is increasing
(iii) C remains constant so there no change in R from (400 K-500K)
(iv) C increases so R increases in range (200 K-300K)
