What do you mean by the following statements —

(i) The heat capacity of a body is 50 J K ^-1?

(ii) The specific heat capacity of copper is 0.4 J g^-1 K^-1 ?

Specific heat capacity of a substance A is 3.8 J g^-1 K^-1 and of substance B is 0.4 J g ^-1 k ^-1. Which substance is a good conductor of heat? How did you arrive at your conclusion?

Name three factors on which the heat energy absorbed by a body depends and state how does it depend on them.

Two blocks P and Q of different metals having their mass in the ratio 2 : 1 are given same amount of heat. Their temperature rises by same amount. Compare their specific heat capacities.
