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

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)

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

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

A container of volume 1m³ is divided into two equal compartments by a partition. One of these compartments contains an ideal gas at 300 K. The other compartment is vacuum. The whole system is thermally isolated from its surroundings. The partition is removed, and the gas expands to occupy the whole volume of the container. Its temperature now would be

The internal energy change in a system that has absorbed 2 Kcals of heat and done 500 J of work is

An ideal gas expands in such a manner that its pressure and volume can be related by equation PV^2 = constant. During this process, the gas is

One mole of an ideal gas expands at a constant temperature of 300 K from an initial volume of 10 litres to a final volume of 20 litres. The work done in expanding the gas is (R = 8.31 J/mole-K)

One mole of O2 gas having a volume equal to 22.4 litres at 0°C and 1 atmospheric pressure is compressed isothermally so that its volume reduces to 11.2 litres. The work done in this process is

A thermally insulated container is divided into two parts by a screen. In one part the pressure and temperature are P and T for an ideal gas filled. In the second part it is vacuum. If now a small hole is created in the screen, then the temperature of the gas will
