A hot-air balloon stays aloft because hot air at atmospheric pressure is less dense than cooler air
Question:
A hot-air balloon stays aloft because hot air at atmospheric pressure is less dense than cooler air at the same pres-sure. If the volume of the balloon 500.0 m3 is and the surrounding air is at 15.0°C, what must the temperature of the air in the balloon be for it to lift a total load of 290 kg (in addition to the mass of the hot air)? The density of air at 15.0°C and atmospheric pressure is 1.23 kg/m3.
