Gaming with Gas Laws

I have made a thermometer which measures temperature by the compressing and expanding of gas in a piston. I have measured that at 100.0 °C the volume of the piston is 22 L. What is the temperature outside if the piston has a volume of 15 L? Which gas law should be used to solve?
