Question

A container with a specific volume “V” changes to “2V.” What happens to the average distance between gas molecules? Assume that pressure and temperature of the gas remain constant.

Answer 1

The average distance between the gas molecules will INCREASE.

Answer 2

Explanation:

It is given that the volume is changing from V to 2V whereas both pressure and temperature remains the same.

So, this also means that number of moles of the substance remains the same but only change in volume is occurring. Therefore, greater volume of container will lead to more space for the movement of molecules.

As a result, molecules will start to move away from each other. Hence, space between them will increase.

Thus, we can conclude that the average distance between gas molecules will increase.
