6. 20/100pts: A hot air balloon is participating in the Albuquerque Balloon Fiesta where the air density is 0.002048 slug/ft3. Balloon and passengers weigh 800-lbs with an air volume, V = 77,000 ft. When the pilot heats up the air inside the balloon with propane burners, at what temperature will the balloon begin to float if the pressure remains the same inside and outside the balloon at 1757 lb/ft?? Use g = 32.1741 ft/s2 and R = 1716 ft-lb/slug"R.
