$A$ metal cube absorbs $2100.0 \ J$ of heat when its temperature is raised by $2^{\circ} C$. If the specific heat of the metal is $900 \ J \ kg^{-1} K^{-1}$, then the mass of the cube is (in $kg$)

Three bodies $A, B$ and $C$ of masses $m, m$ and $\sqrt{3}m$ respectively are supplied heat at a constant rate. The change in temperature $\theta$ versus time $t$ graph for $A, B$ and $C$ are shown by $I, II$ and $III$ respectively. If their specific heat capacities are $S_A, S_B$ and $S_C$ respectively,then which of the following relations is correct? (Initial temperature of body is $0\,^{\circ}C$)

What is the heat capacity of a substance?

Define specific heat capacity and write its $SI$ unit.

Thermal capacity of a body depends on

If some heat is given to a metal of mass $100 \ g$,its temperature rises by $20^{\circ} C$. If the same heat is given to $20 \ g$ of water,the change in its temperature (in $^{\circ} C$) is (The ratio of specific heat capacities of metal and water is $1: 10$).
