why does changing the volume of a container change the pressure of the gas in it?\nchanging the volume reduces the number of molecules so they hit the walls of the container less often.\nchanging the volume reduces the force with which the molecules hit the walls of the container.\nchanging the volume increases the speed of the molecules so they hit the walls of the container more often.\nchanging the volume increases the area that the molecules collide with so the force is spread over a larger area.

Answer

Brief Explanations:

According to the kinetic - molecular theory of gases, pressure is due to the collisions of gas molecules with the container walls. When the volume of the container changes, if the volume decreases, the same number of molecules are in a smaller space, so they hit the walls more frequently, increasing pressure. If the volume increases, the molecules have more space and hit the walls less frequently, decreasing pressure. Also, when the volume changes, the area of the walls that the molecules collide with changes. When the volume increases, the area of the walls increases, and the force exerted by the molecules is spread over a larger area, reducing the pressure per unit area (pressure).

Answer:

Changing the volume increases the area that the molecules collide with so the force is spread over a larger area.
