Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).

What would heating the gas in an air balloon make the balloon rise?

Simple...hot air rises..


Why would heating the gas in a hot air balloon make the balloon rise?

When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.


Why would a hot air balloon pilot heat the air in the balloon to make it rise?

Heating the air in the balloon makes it less dense than the surrounding air, causing the balloon to become buoyant and rise. As the air inside the balloon cools, it becomes denser and the balloon descends. This process allows the pilot to control the altitude of the balloon.


Why would heating the gas in air balloon make balloon rise?

if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.


Why would heating a hot air balloon make the balloon rise?

Heating the air inside the balloon makes it less dense than the surrounding air, causing it to become buoyant and rise. As the air inside the balloon is heated, it expands and its volume increases. This expansion pushes the surrounding air down, creating a lift force that allows the balloon to ascend.

Will a balloon rise if the air inside is hot?

The heating of the air through the use of a burner is what makes balloons rise.


The air in hot air balloon is heated to make the balloon rise?

Yes, the air inside the balloon is heated with a burner, which causes it to become less dense than the surrounding cooler air. This difference in density creates buoyancy, lifting the balloon and its passengers off the ground.


Why did they call it the hot air balloon?

A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.


Why Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?

Heating the air makes less air take up the same space, so the air inside the balloon is lighter than the surrounding air. The pilot turns off the burner to help the balloon to maintain the current altitude or to descend.


Why is an hot air balloon called a hot air balloon?

A hot air balloon is called such because it is filled with hot air to make it rise. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to float upwards.


What force makes a hot air balloon rise up into the air?

The upthrust exerted by surrounding air on the balloon.
