An empty flexible bioreactor is purged with a disinfecting gas. The gas is added to the reactor at 25 degree Celsius and heated up to 80 degree Celsius. The gas expands during the heating such that the bioreactor maintains a constant pressure of 1.0 atm. You can assume that the gas has the properties of air. A) Use equation of state to determine the specific volume (m^3/kg) of gas of each temperature? B) If the specific enthalpy of the gas increases by 352 KJ/kg as the gas is warmed, what is the change in specific internal energy of the gas between the two states ?
