Question 253

A fixed mass of gas is contained within a sealed syringe at an initial pressure of 120 kPa. The plunger is slowly moved until the pressure becomes 90 kPa. The final volume of the gas is 80 cm3. The temperature of the gas does not change. What is the volume of the gas before the plunger is moved?
