Solution

1. Gases deviate from ideal gas behaviour under low temperature or high pressure.

2. This is because, at low temperature the speed of the molecules decreases significantly and due to this average volume of gas is very much less than that of container. Under high pressure, the velocity of the molecules is very high that make them difficult to compress.

3. Ideal gases are easily compressible and occupy the volume equal to that of container.

Q. Under what conditions gases generally deviate from ideal behaviour?

Q. Ideal gases and real gases behave in similar ways under certain conditions. However, under specific conditions, real gases deviate from ideal behaviour. Which gas deviates most from ideal behavior?

Q. Statement A: Gases deviate from their ideal behaviour at low temperatures.
Statement B: At low temperatures, the molecular attractions become significant. This leads to a deviation from the ideal behaviour of a gas.

Q. Under what condition real gases obey ideal gas behaviour?

According to the kinetic-molecular theory of gases, due to large distance of separation, forces of attraction or repulsion between them becomes negligible.
