Yes, hot air always rises while cold air sinks

Will a balloon rise higher with hot air or cold air?

Hot air


Does helium contract in cold weather and cause a helium balloon to sink and if warmed will it rise again?

Helium will contract in cold weather, but that may not cause a balloon filled with it to sink since the air will also contract - and by about the same amount - so the relative densities of the helium and the surrounding are would remain about the same and the buoyancy of a helium filled balloon would remain


How does hot and cold air have an effect on an balloon?

If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.


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 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.

How do you make the air balloon rise higher?

By puting more hot air into it thus creating lift. hot air rises cold air lowers, so when the hot air is traped it has no were else to go but up so it brings the hot air balloon with it. And to decend a flap at the the top of the balloon opens by itsefl to let hot air out and to let you down.


Why do hot air balloon rise up?

because the density in the balloon is heated so it rises higher than it being unheated


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).


Why does a hot air balloon rise when it is heated and sink wen it is cooled?

If it is cooled its gets extremely cold from the helium,and when the heat is in the balloon it keeps it warm when its in the helium


What kind gas is used in hot air balloon?

No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.


How hot and cold temperature affect air balloon?

Hot temperatures can cause the air inside the balloon to expand, making the balloon rise. Cold temperatures can cause the air inside the balloon to contract, making the balloon descend. Changes in temperature can also affect the buoyancy and stability of the balloon during flight.
