Analysis

  1. How does the volume of the gas change with pressure?




  2. What product or ratio of properties remains constant (PT, TV, P/V, V/T, etc.)? When you have decided, label the "Constant?" column with the proper term
     and fill in the values.




  3. Derive the relationship between V1 and V2, the volumes of a gas at two pressures, P1 and P2.




  4. If a sample of gas at 25.2°C has a volume of 536 mL at 637 torr, what will its volume be if the pressure is increased to 712 torr?
