What is ballast in a balloon?
By heating the air inside the balloon with the burner, it becomes lighter than the cooler air on the outside, causing the balloon to float upwards. The final kind is a pure gas balloon which doesn’t use hot air and the altitude can only be controlled by dropping ballast or venting the gas.
Why is air density important in hot air balloons?
This is the density of air, which is the mass per unit of volume of Earth’s atmosphere. Hot air balloons use hot air to create buoyancy, which results in allowing the balloon to float and carry passengers riding in the basket. The hot air inside of the balloon is less dense than the surrounding air.

Will bleach spray kill wasps?
