At a constant temperature, the volume decreases.  What happens to the pressure?

• increases
• decreases
• stays the same

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.
