Question

Gases at low temperature and high pressure show a large deviation from an ideal behaviour.

(a) True

(b) False

The question was asked in a national level competition.

My query is from Gases in division Kinetic Theory of Gases of Engineering Physics I

Answer 1

Right answer is (a) True

To elaborate: At low temperature and high pressure, the intermolecular attractions become appreciable. Moreover, the volume occupied by the gas molecules cannot be neglected in comparison to the volume of the gas. Hence the real gases show large deviations from an ideal gas.
