A cylinder with a height of 1.30 and an inside diameter of 0.110 is used to hold propane gas (molar mass 44.1 ) for use in a barbecue. It is initially filled with gas until the gauge pressure reads 1.80×106 and the temperature is 22.0. The temperature of the gas remains constant as it is partially emptied out of the tank, until the gauge pressure reads 3.70×105
