In 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. (a) (i) and (iii) (b) (i) and (iv) (c) (ii) and (iii) (d) (ii) and (iv)

The correct answer is (c) (ii) and (iii). When some hydrogen gas leaks out (ii), fewer molecules remain, increasing intermolecular distance. When the container’s volume increases (iii), molecules spread out to occupy the larger space, increasing their distance. Class 9th ...
