Properties of Gas
    can observe with our senses

  Pressure (p)
  temperature (T)
  mass (m)
  volume (v)

For a given mass at a constant temperature  Volume is inversely related  to pressure  If pressure increases, the volume decreases  If pressure decreases, volume increases  Graph     Shows Inversely proportional relationship    Slope: nonlinear line

For a given mass at a constant pressure  Volume is directly proportionate to temperature  If the temperature goes up so does volume  If the temperature goes down so does volume Graph     Shows Directly proportional relationship    Slope: linear line
