Answer:
A.the gas particles strike the walls of the container more often
Explanation:
Boyle's law states that for a constant mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume.
Mathematically:
[tex]p\propto \frac{1}{V}[/tex]
where
p is the pressure of the gas
V is its volume
The reason of this relationship is that when the volume of the gas is decreased, the particles of the gas collide more frequently with the walls of the container, and therefore the average force exerted by the particles of the gas on the wall is greater; as a result, the pressure exerted by the particles of the gas on the wall is also greater.
Therefore, the correct option is
A.the gas particles strike the walls of the container more often
