Question

Under which of the following conditions, the distance between the molecules of hydrogen gas would increase? (i) Increasing pressure on hydrogen contained in a closed container (ii) Some hydrogen gas leaking out of the container (iii) Increasing the volume of the container of hydrogen gas. (iv) Adding more hydrogen gas to the container without increasing the volume of the container​

Answer 1

ii and iii

Step by Step

When hydrogen gas leaks out of the container, the molecules of the gas remaining in the container have more free space. Hence, distance between the gas molecules increases. By increasing the volume of the container also increases the distance between the molecules.

Answer 2

(ii) and (iii)

(ii) Some hydrogen gas leaking out of the container (iii) Increasing the volume of the container of hydrogen gas.
