  • If the volume of a fixed mass of gas at a constant temperature is decreased, the pressure increases because
    • the distance the particles travel between each impact with a container wall is smaller
    • the number of impacts per second increases, so the total force of impacts increases.
  • Similarly, if the volume is increased, the pressure decreases. This is because
    • the distance the particles travel between each impact with a wall of the container is greater
    • the number of impacts per second decreases, so the total force of the impacts decreases.
  • Pressure x volume = constant
