An increase in the volume of a closed container filled with air would have what effect on the pressure of the container?

Question

BlackTom AI · Accepted Answer

When a gas is confined in a closed container and the volume is increased, the gas molecules have more space to move around, which means they collide with the container walls less frequently. This reduced collision rate leads to a lower pressure inside the container.

Option A: 'A temporary effect' — The pressure change is governed by the immediate relationship between volume and pressure for a gas in a closed system (assuming temperature is constant, i.e., isothermal conditions). It is not simply a temporary or transient effect; once the volume is increased and the gas expands, the pressure stabilizes at a lower value (per Boyle's law).

Option B: 'Decrease in the pressure' — This matches the fundamental gas law P ∝ 1/V for a fixed amount of gas at constant temperature. Increasing V decreases P, so this statement is consistent with the correct physical principle.

Option C: 'No effect' — This would imply pressure is independent of volume, which contradicts the core relationship described by gas laws. In a closed container with a fixed amount of gas, changing volume does affect pressure.

Option D: 'Increase in the pressure' — This is the opposite of what actually happens when volume increases; expanding the container reduces the frequency of molecular collisions with the walls, thereby lowering pressure rather than raising it.
