Consider a hot-air balloon. The deflated balloon, gondola, and 2 passengers have a combined mass of 315 kg. When inflated, the balloon contains 863 m^3 of hot air. Find the temperature (degrees C) of the hot air required to lift the balloon off the ground. The air outside the balloon has a temperature of 20.2 degrees C and a pressure of 0.916x10^5 Pa. The pressure of the hot air inside the balloon is the same as the pressure of the air outside the balloon. The molar mass of air is 29 g/mol. Hint: First find the density of the air outside the balloon. Then use Archimedes' principle to find the density required for the air inside the balloon. Then find the temperature of the air inside the balloon.
