A Diagram Of A Hot Air Balloon Of The Density. The average density of the balloon decreases less than that of the surrounding air. When full of helium what is the maximum mass it can lift off the ground.
The weight of the displaced air is reduced. ρ density kgm 3 example mass of air at temperature 20 o c. The speed of a sound wave in air depends upon the properties of the air mostly the temperature and to a lesser degree the humidity.
A rising balloon stops rising when it and the displaced air are equal in weight.
The air that you blow into the balloon fills up the whole balloon. You can do this very easily by heating the air. M 10 m 3 1205 kgm 3 1205 kg example lifting force of a hot air balloon. The temperature of the.
