30. The behaviour of a monatomic gas such as helium cannot be regarded as an ideal gas

when it is kept at high pressure and low temperature. Which of the following is / are the

main reasons?

(1) At high pressure, the molecules become closer which the actual volume of the molecules

becomes more significant compared with measured volume of the container. Therefore, the

measured volume of the gas is much greater than the available volume in which the

molecules can move.

(2) At low temperature, the molecules move so slow that makes weak attractive forces

between the molecules become more significant compared with the force of collision on the

container walls. Therefore, the pressure would be reduced greatly by the said weak

attractive forces on any molecules moving toward the container walls.

(3) At low temperature, the molecules move so slow that makes the duration time of collision

are more significant compared with the time spent between collisions. Therefore, the gas

pressure would be reduced greatly due to a slower rate of change of momentum of the gas

molecules during collision with the wall of the container.
