Define:Critical temperature.

Critical temperature of NH_3 and CO_2 are 405.5 K and 304.10 K respectively. Which of these gases will liquiefy first when you start cooling from 500 K to their critical temperature.

The critical temperature of NH_(3),CO_(2) and O_(2) gases are 405.6K, 304.1 K and 154.2 K, respectively. If the gases are cooled from 500 K to their respective critical temperature, then which gas will be liquefied first?

Define : kraft temperature

What is the Boyle's temperature and critical temperature? Give the relation between them.

Why the gas do not liquidity at above the critical temperature?

It is easier to liquefy a gas with higher critical temperature-explain.

The pressure and temperature of a gas are P and T respectively. If the critcal pressure and critical temperature of the gas be P_(c) and T_(c) respectively, then liquefacction will be possible when-

What do you mean by surfactant? Give example. WJiat is the magnitude of surface tension at critical temperature?

Arrange the following gases in order of their critical temperature: NH_(3),H_(2)O,CO_(2),O_(2) -

A real gas follows van der waals equation. Find the compressibility for 1 mol of the gas at its critical temperature.
