A hot air balloon is floating above the ground in a stable flight.
At a pressure of 1 atm and a temperature of , dry air has a density of 1.2256 g/L. The dry air inside the balloon has a temperature of , and a density of 1.0849 g/L.
The lifting capacity of a hot air balloon is equal to the difference in the mass of the cool air displaced by the balloon and the mass of the gas in the balloon.
How much lighter is 1.00 L of dry air inside the balloon than 1.00 L of dry air outside the balloon?
A typical balloon has a volume of L. What is the lifting force of such a balloon?
