Question

Nitrogen gas is filled in a container. In which of the following conditions, the distance between the molecules of nitrogen gas would increase?

• A. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Increasing pressure on nitrogen contained in a closed container.
• B. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Some nitrogen gas leaking out of the container.
• C. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Increasing the volume of the container of nitrogen gas
• D. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Adding more nitrogen gas to the container without increasing the volume of the container

Answer 1

Answer: (B), (C)

The correct options are
B <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Some nitrogen gas leaking out of the container.
C <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Increasing the volume of the container of nitrogen gas

$\bullet$ On increasing pressure gas particles come closer to each other and space between them decraeses.
$\bullet$ When gas leaks from the container, the number of particles of gas decreases inside the container. Hence distance between the molecules of nitrogen gas would increase.
$\bullet$ On increasing the volume of the container, the same number of particles will get distributed in larger volume. Hence distance between the molecules of nitrogen gas would increase.
$\bullet$ 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.
