A balloon is slowly compressed at an atmospheric pressure of 649 torr and temperature of 169 °R. The temperature inside the balloon remains at the atmospheric temperature, while the volume changes from 0.0256 bbl (US) to V2 ft3, and gage pressure inside the balloon increases from 226 kgf/m2 to 0.672 lbf/in2.
Note: Use the ideal gas law — absolute pressure·volume=number of moles·ideal gas constant·absolute temperature. The ideal gas constant is 8.134 J·mol-1·K-1.
