If 500 mL of a gas A at 1000 Torr and 1000 mL of gas B at 800 Torr are placed in a 2L container, the final pressure will be

Which of the following is not the postulate of the kinetic theory of gases?

Maximum deviation from ideal gas is expected from

The behavior of real gases approach ideal behavior at

Positive deviation from ideal gas behavior takes places because of

Critical temperatures of $H_2O,NH_3,CO_2$ and $O_2$ are 647K, 405.6K, 304.10K, and 154.2K respectively. If the cooling starts from 500K to their critical temperature, the gas that liquefies first is

The compressibility factor for a real gas at high pressure is

The compressibility of a gas is less than unity at NTP.

A gas can be liquefied 

On heating a liquid, its viscosity
