Be sure to answer all parts. The air in a hot-air balloon at 785 torr is heated from 15.0°C to 41.0°C. Assuming that the moles of air and the pressure remain constant, what is the density of the air at each temperature? (The average molar mass of air is 29.0 g/mol.) Density at 15.0°C g/L? Density at 41.0°C g/L?

Challenge problem. (extra credit) Consider a hot-air balloon. The deflated balloon, gondola, and two passengers have a combined mass of 315 kg. When inflated, the balloon contains 912 m3 of hot air. Find the temperature (?C) of the hot air required to lift the balloon off the ground. The air outside the balloon has a temperature of 20.2?C and a pressure of 0.916 × 10^5 Pa. The pressure of the hot air inside the balloon is the same as the...

How hot is the air in the top (crown) of a hot air balloon? Information from Ballooning: The Complete Guide to Riding the Winds, by Wirth and Young (Random House), claims that the air in the crown should be an average of 100°C for a balloon to be in a state of equilibrium. However, the temperature does not need to be exactly 100°C. What is a reasonable and safe range of temperatures? This range may vary with the size and...
