Hard
In which of the following conditions, the distance between the molecules of a gas would increase? (a) Increasing pressure on gas in a closed container (b) Some gas leaking out of the container (c) Increasing the volume of the container of the gas (d) Adding more gas to container without increasing volume
Explanation
Explanation
When gas leaks out, fewer molecules remain in the same volume, spreading them further apart. When the container's volume is increased, the same number of molecules occupy more space, also increasing the distance between them. So (b) and (c) both increase molecular distance, while (a) and (d) do the opposite (increase crowding).
PRO TIP
Re-check your working by substituting the answer back into the original question.
