How many times a diatomic gas should be expanded adiabatically so as to reduce the root mean square velocity to half?

A given system undergoes a change in which the work done by the system equals the decrease in its internal energy. The system must have undergone an

During the adiabatic expansion of 2 moles of a gas, the internal energy was found to have decreased by 100 J. The work done by the gas in this process is

In an adiabatic expansion of a gas initial and final temperatures are T₁ and T₂ respectively, then the change in internal energy of the gas is

The work of 146 kJ is performed in order to compress one kilo mole of a gas adiabatically and in this process the temperature of the gas increases by 7°C. The gas is (R = 8.3 mol^–1 K^–1)

At N.T.P. one mole of diatomic gas is compressed adiabatically to half of its volume, γ = L41. The work done on gas will be

A gas is being compressed adiabatically. The specific heat of the gas during compression is

The process in which no heat enters or leaves the system is termed as

Two moles of an ideal monoatomic gas at 27°C occupies a volume of V. If the gas is expanded adiabatically to the volume 2V, then the work done by the gas will be [γ = 5/3, R = 8.31 J/mol K]
