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.
Why does a balloon need hot air?
A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
Why can air balloon rise to the sky?
it can rise because of the helium and the gases help make it rise to the sky
How do convection currents make a hot air balloon to rise?
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
Why does the balloon rise?
because it contains helium that is lighter than air
Why would heating the gas in balloon make the 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 does heating the air in hot air balloon make it rise?
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).
When does a air balloon rise?
A hot air balloon rises because when hot air is added it is intended to rise and when the hot air balloons wants to land, hot air is decreased.
What is the use of air in air balloon?
with out the hot air the balloon would not rise
Why do balloons rise in the air?
A balloon rises in the air only if the balloon has a lower mass than an equal volume of the air surrounding it.That might be the case if the balloon were filled with a light gas such as helium, for example. The balloon rises because the pressure of the air around it pushes it up in the same way that water causes an air bubble to rise.
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 do certain gases allow a balloon to rise?
Because the gases filling the balloon are lighter than the surrounding air.
