Q.
A gas deviates from ideal behaviour at a high pressure because its molecules
A) Attract one another
B) Show the Tyndall effect
C) Have kinetic energy
D) Are bound by covalent bonds
Explanation
(a)
At high pressure, the volume is decreased appreciably, so the attractive forces become large and the molecules are crowded together. Thus, pressure correction is necessary and the gas deviates more from ideal behaviour.
