Specific 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

The volume of $n$ moles of an ideal gas with degree of freedom $f$ is varied according to the law $V=\frac{a}{T}$ where $a$ is a constant. The molar specific heat of the gas at constant pressure is

Two identical systems, with heat capacity at constant volume that varies as $C_v=b{T}^3$ (where $b$ is a constant) are thermally isolated. Initially, one system is at a temperature $100\mathrm{ }\mathrm{K}$ and the other is at $200 \mathrm{K}$ . The systems are then brought to thermal contact and the combined system is allowed to reach thermal equilibrium. The final temperature (in $\mathrm{K}$ ) of the combined system is $\alpha$. Write the value of $\left[\alpha \right],$ where $\alpha$ is the greatest integer function.

During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its absolute temperature. The ratio $\frac{C_{\mathrm{P}}}{C_{\mathrm{V}}}$  for the gas is $\frac{x}{2}$. Find $x$.

The piston is massless and the spring is ideal and initially streched the piston cylinder arrangement encloses an ideal gas. If the gas is heated quasistatically the $PV$ graph.

Figure shows a long fixed container which has two freely movable (without friction) pistons. The container and pistons are made of a thermally conducting material that allows very slow transfer of heat. First compartment of container is filled with $2$ moles of an ideal monoatomic gas at $200 \mathrm{K}$ and the $2^{\mathrm{nd}}$ compartment is filled with $1$ mole of ideal diatomic gas at $500 \mathrm{K}$. Initially pressure of gases in both the compartment is same and equal to atmospheric pressure. Temperature of atmosphere is $300 \mathrm{K}$. Finally gases achieve equilibrium. '$R$' is the gas constant

An ideal gas which undergoes through a process $V=a{T}^2;$ starting at $T_0$ and ends at $2T_0$. $a$ is a constant. The molar heat capacity of the gas if it is monoatomic is $\frac{n}{2}R$; What is $n$ ?

Two litres of water at initial temperature of $27°\mathrm{C}$ is heated by a heater of power $1 \mathrm{kW}$ in a kettle. If the lid of the kettle is open, then heat energy is lost at a constant rate of $160 \mathrm{J} {\mathrm{s}}^{-1}$. The time in which the temperature will rise from $27°\mathrm{C}$ to $77°\mathrm{C}$ is,
