A chamber is filled with gas and pressurized to 2 atm(g) and then is connected to a second chamber filled with the same gas at 0 (zero) atm (g) pressure. The final pressure is measured to be 1 atm(g). A steel cylinder that has the volume of 20 cc is then placed in first chamber and the chamber is pressurized to 2 atm(g). The chamber is then connected to a second chamber at 0 (zero) atm (g) pressured and the final pressure is measured to be 0.89 atm (g). Determine the volumes of the both chambers. Assume the gas behaves as an ideal gas.
