Question:
The balloon portion of a dirigible is filled with 5000 moles of helium (Figure 2-13). Initially, the helium is at P = 1 atm and T = 25°C. As the dirigible gains altitude, the pressure drops to P = 0.95 atm, and the temperature drops to T = 15°C. Find the changes in volume, internal energy, and enthalpy for the helium in this process, assuming helium has a constant ideal gas heat capacity of C*V = (1.5)R.
