In changing the state of thermodynamics from A to B state, the heat required is Q and the work done by the system is W. The change in its internal energy is

1 mm³ of a gas is compressed at 1 atmospheric pressure and temperature 27°C to 627°C. What is the final pressure under adiabatic condition (γ for the gas = 1.5)

An ideal gas at a pressure of 1 atmosphere and temperature of 27°C is compressed adiabatically until its pressure becomes 8 times the initial pressure, then the final temperature is (γ = 3/2)

Helium at 27°C has a volume of 8 litres. It is suddenly compressed to a volume of 1 litre. The temperature of the gas will be [γ = 5/3]

A diatomic gas initially at 18°C is compressed adiabatically to one-eighth of its original volume. The temperature after compression will be

In thermodynamic processes which of the following statements is not true

In a reversible isochoric change

Which relation is correct for isometric process?

N moles of an ideal diatomic gas are in a cylinder at temperature T. Suppose on supplying heat to the gas, its temperature remains constant, but n moles get dissociated into atoms. Heat supplied to the gas is

An ideal gas follows a process described by PV² = C from (P1, V₁T₁) to (P2 V2 ⊤2) (C is a constant). Then
