Options

A. pressure is temperature are both high
B. pressure is temperature are both low
C. pressure is high temperature are both low
D. pressure is low temperature are both high

Answer

D

Explanation

(d) A real gas behaves as an ideal gas when the average
distance between the gas molecules is large enough
so that (i) the force of attraction between the gas
molecules becomes almost zero (ii) the actual volume
of the gas molecules is negligible as compared to the
occupied volume of the gas.
The above conditions are true for low pressure and
high temperature.
