In a cyclic process, a gas is taken from state $A$ to $B$ via path $-I$ as shown in the indicator diagram and taken back to state $A$ from state $B$ via path $-II$ . In the complete cycle

Pressure versus temperature graph of an ideal gas is as shown in figure. Density of the gas at point $A$ is ${\rho _0}$. Density at point $B$ will be

If heat is added at constant volume, $6300\,\,J$ of heat are required to raise the temperature of an ideal gas by $150\,\,K$. If instead, heat is added at constant pressure, $8800$ joules are required for the same temperature change. When the temperature of the gas changes by $300\,\,K$, the internal energy of the gas changes by ….. $J$

One mole of an ideal gas is taken through an adiabatic process where the temperature rises from $27^{\circ} {C}$ to $37^{\circ} {C}$. If the ideal gas is composed of polyatomic molecule that has $4$ vibrational modes which of the following is true?

When an ideal diatomic gas is heated at constant pressure, the fraction of the heat energy supplied which increases the internal energy of the gas, is
