Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which of the following conditions the distance between 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.
A
(I), (III)
B
(I), (IV)
C
(II), (III)
D
(II), (IV)
Explanation: 

Detailed explanation-1: -Hence the correct answer is (C). i.e leakage of hydrogen gas and increasing the volume of the container will increase the distance between the molecules.

Detailed explanation-2: -(ii) Some hydrogen gas leaking out of the container would accommodate more space so the distance between the molecules of hydrogen gas would increase, thus it is the correct answer.

Detailed explanation-3: -By increasing the pressure or by adding Hydrogen without increasing container volume inter-molecular interaction would decrease.

Detailed explanation-4: -In these statements the distance between the molecules of hydrogen gas would increase and hence it is correct.

Detailed explanation-5: -∙ On increasing the amount of the gas in the container, more number of particles will get distributed in same volume. Hence distance between the molecules of nitrogen gas would decrease.
