The ratio γ for inert gases is:

A bottle of ammonia and a bottle of HCl connected through a long tube are opened simultaneously at both ends. The white ammonium chloride ring first formed will be

In the equation PV = nRT which one cannot be numerically equal to R.

Gases deviate from the ideal gas behaviour because their molecules :

With increase of pressure, the mean free path:

In a closed flask of 5 litres, 1.0 g of H₂ is heated from 300 to 600 K. Which statement is not correct?

At constant temperature, in a given mass of an ideal gas

Any gas shows maximum deviation from ideal gas at

A closed vessel contains equal number of nitrogen and oxygen molecules at pressure of P mm. If nitrogen is removed from the system, then the pressure wii be :

A real gas most closely approaches the behaviour of an ideal gas at :
