For free expansion of the gas which of the following is true

A monoatomic gas (γ = 5/3) is suddenly compressed to 1/8 of its original volume adiabatically, then the pressure of the gas will change to times its initial pressure

If γ= 2.5 and volume is equal to times to the initial 1/8 volume then pressure P’ is equal to (Initial pressure = P)

Consider two containers A and B containing identical gases at the same pressure, volume and temperature. The gas in container A is compressed to half of its original volume isothermally while the gas in container B is compressed to half of its original value adiabatically. The ratio of final pressure of gas in B to that of gas in A is

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

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
