what is true of the heat content for a system at constant pressure

For each of the given initial state parameters, select the appropriate dew point temperature: Note:Tdb - dry bulb temperature, F Twb - wet bulb temperature, F Tdp - dew point temperature, F h -enthalpy, Btu/lbair RH - relative humidity, % ω  - humidity ratio, lbH2O/lbair v - specific volume, ft3/lbair                                                                        Tdb=70F & RH=70%                                                                        Tdb=65F & RH=30%                                                                        Tdb=90F & RH=30%                                                                        Tdb=70F & RH=100%                                                                        Tdb=100F & RH=60%

2) Two glass bulbs, one on the left with a volume of 2 liters and the other on the right with avolume of 6 liters, are connected to one another by a thin tube that is initially closed by astopcock. The bulb on the left has 0.1 moles of ideal gas, and the bulb on the right isevacuated. The system is in thermal equilibrium with the surroundings at 300K. When thestopcock is opened, the gas flows out to fill both bulbs. Calculate A for this process. If wewere to insert a propeller to extract work as the gas flows from left to right, what is themaximum amount of work that we could possibly extract?
