Answer:
Changing the volume increases the area that the molecules collide with so the force is spread over a larger area.
Explanation:
The volume of a container is the space within the container. This is the amount of void the gas can occupy.
When the volume of a container is changed, the space either increases or decreases.
- An increase in volume creates more space within the container.
- This spreads out the force over a larger area.
When the volume of the container is reduced,
- the force is confined to much smaller space.
The frequency of collision is higher for tiny spaces.
But lower for a large volume.
