A rigid diatomic ideal gas undergoes an adiabatic process at room temperature. The relation between temperature and volume of this process is $TV^x = \text{constant}$. Then $x$ is

A carnot engine having an efficiency of $\frac{1}{10}$ as heat engine, is used as a refrigerator. If the work done on the system is $10 \text{ J}$, the amount of energy absorbed from the reservoir at lower temperature is

If the pressure of an ideal gas contained in a closed vessel is increased by $0.5\%$, the increase in temperature is $2^\circ\text{C}$. The initial temperature of the gas is

During the free expansion of an ideal gas, which of the following physical quantity remains constant

The specific heat at constant volume for a monoatomic gas is $0.075\text{ cal/kg}\cdot\text{K}$ and its gram molecular specific heat is $3\text{ cal/mol}\cdot\text{K}$. Then mass of one atom of that gas is
