Heat given to a body which raises its temperature by $1\ ^oC$ is

The specific heat of a substance at temperature $T^{\circ}C$ is given by $C = \alpha T^2 + \beta T + \gamma$. The amount of heat required to raise the temperature of a mass $m \, g$ of the substance from $0^{\circ}C$ to $T_o^{\circ}C$ is .......

Two spheres are made of the same material and have a diameter ratio of $1 : 2$. The ratio of their heat capacities is equal to ......

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

$A$ substance is cooled at a constant power. Its temperature vs time graph is shown. The value of $S_{solid} : S_{liquid} : S_{gas}$ is:
