For a gas γ = 7/5. The gas may probably be

The molar specific heat at constant pressure of an ideal gas is (7/2)R. The ratio of specific heat at constant pressure to that at constant volume is

The degrees of freedom of a stationary rigid body aboutits axis will be

10 moles of an ideal monoatomic gas at 10°C is mixed with 20 moles of another monoatomic gas at 20°C. Then the temperature of the mixture is

Two cylinders of equal size are filled with equal amount of ideal diatomic gas at room temperature. Both the cylinders are fitted with pistons. In cylinder A the piston is free to move while in B position is fixed. When same amount of heat is supplied to both the cylinders, the temperature of the gas in cylinder A raises by 30 K. What will be the rise in temperature of the gas in cylinder B?

If the internal energy of n₁ moles of He at temperature10 T is equal to the internal energy of n₂ mole ofhydrogen at temperature 6 T. The ratio of n₁/ n₂is

A cylinder of fixed capacity (of 44.8 litres) contains 2 moles of helium gas at STP. What is the amount of heat needed to raise the temperature of the gas in the cylinder by 20°C (Use R = 8.31 J mol^–1 K^–1)

The pressure is exerted by the gas on the walls of the container because
