Write the value of the specific heat capacity of water with its unit.

Two substances $A$ and $B$ of the same mass are heated at a constant rate. The variation of temperature $\theta$ of the substances with time $t$ is shown in the figure. Choose the correct statement.

The thermal capacity of $40\, g$ of aluminium (specific heat $= 0.2\, cal/g/^{\circ}C$) is ........ $cal/^{\circ}C$.

Give the $SI$ unit of heat capacity. Write the dimensional formula of heat capacity.

What is specific heat? Write its equation and unit,and on what does it depend?

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 $0\,^{\circ}C$)
