Heat Capacity

A body of mass $10 \mathrm{kg}$ falls from a height of$25 \mathrm{m}$ and rebounds to a height of $0.50 \mathrm{m}$. If the loss in energy goes into heating the body, then the rise in temperature will be nearly: (specific heat of material is $25.2 \mathrm{J} {\mathrm{kg}}^{-1} {\mathrm{K}}^{-1}$)

Below is a graph between change in internal energy and temperature for a system placed in a constant volume.

The slope of the graph is known as

What does the latent heat of fusion measure?

 Which are three types of latent heat?

What is specific heat capacity of a substance?

Two different liquids of same mass are kept in two identical vessel, which are placed in a freezer that extracts heat from them at the same rate causing each liquid to transform into a solid. The schematic figure below shows the temperaure $T$ vs time $t$ plot for the two materials. We denote the specific heat in the liquid states to be $C_{L1}$ and $C_{L2}$ for materials $1$ and $2$ respectively, and latent heats of fusion $U_1$ and $U_2$ respectively.

Choose the correct option.

A current carrying wire heats a metal rod. The wire provides a constant power $\left(\mathrm{P}\right)$ to the rod. The metal rod is enclosed in an insulated container. It is observed that the temperature $\left(\mathrm{T}\right)$ in the metal rod changes with time $\left(\mathrm{t}\right)$ as:

$\mathrm{T}\left(\mathrm{t}\right)={\mathrm{T}}_0\left(1+\mathrm{\beta }{\mathrm{t}}^{1/4}\right)$

where $\mathrm{\beta }$ is a constant with appropriate dimension while ${\mathrm{T}}_0$ is a constant with dimension of temperature. The heat capacity of the metal is:
