	In an isothermal expansion
	In an isothermal reversible expansion, if the volume of 96 gm of oxygen at 27°C is increased from 70 litres to 140 litres, then the work done by the gas will be
	A vessel containing 5 litres of a gas at 0.8 m pressure is connected to an evacuated vessel of volume 3 litres. The resultant pressure inside will be (assuming whole system to be isolated)
	For an isothermal expansion of a perfect gas, the value of $\frac{\Delta P}{P}$ is equal
	The gas law $\frac{PV}{T}=$ constant is true for
	One mole of ${{O}_{2}}$ gas having a volume equal to 22.4 litres at ${{0}^{o}}C$ and 1 atmospheric pressure in compressed isothermally so that its volume reduces to 11.2 litres. The work done in this process is
	If a gas is heated at constant pressure, its isothermal compressibility
	Work done per mol in an isothermal change is
	The isothermal Bulk modulus of an ideal gas at pressure P is
	In isothermal expansion, the pressure is determined by
