What happens to the particle bombardment when the volume of a gas increases?

When the volume of a gas increases, the particle bombardment, which refers to the frequency of gas particles colliding with the walls of the container, decreases. This is due to the fact that as the volume increases, the gas particles have more space to move around, which results in a lower collision rate against the walls.

The principle behind this phenomenon can be understood through the ideal gas law, which states that for a given number of particles at constant temperature, an increase in volume leads to a decrease in pressure. Since pressure is defined as the force exerted per unit area and is directly related to the frequency of the particles striking the container walls, a larger volume means that the same number of particles is spread out over a greater area.

Therefore, with fewer collisions happening per unit time and area, the overall bombardment of particles on the container walls decreases as the volume increases.
