Which of the following explains the change in pressure when volume increases?
As the volume increases, the particles slow down, causing less collisions and less pressure.
As the volume increases, the particles speed up, causing more collisions and more pressure.
As the volume increases, the particles have more space to move and collide less with the walls , causing pressure to decrease.
As the volume increases, the particles have more space to move and collide less with the walls , causing pressure to increase.
