Question

.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)​

Answer 1

Explanation:

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 is :- D) 2 and 4.

Answer 2

Answer:

(ii) Some hydrogen gas leaking out of the container

(iv) Adding more hydrogen gas to the container without increasing the volume of the container

(d) (ii) and (iv)
