Question

Consider an ideal gas contained in a vessel. If the intermolecular interaction suddenly begins to act, which of the following will happen:

• A. the observed pressure decreases
• B. the observed pressure increases
• C. the observed pressure remains same
• D. none of these

Answer 1

The correct option is A the observed pressure decreases

Consider an ideal gas contained in a vessel. If the intermolecular interaction suddenly begins to act, the observed pressure decreases as the molecules will come closer and the number of collisions with the walls of container will decrease.
