Why does a balloon filled with cold air falls to the ground?
Cold air is denser than warm air, therefore a balloon filled with cold air will weigh more than an identically sized balloon full of warm air. This extra weight causes the balloon to sink bellow warmer air. Cold air is denser than warm because as molecules become cooler they move more slowly causing them to be closer together.
What determines if a balloon filled with a gas will rise or sink in the air?
A balloon filled with a gas will rise or sink depending on the density of the gas inside compared to the surrounding air. If the gas inside is less dense than the surrounding air, the balloon will rise. If the gas inside is more dense, the balloon will sink.
Why do balloons filled with air sink?
Balloons filled with air are denser than the surrounding air, causing them to sink. The weight of the balloon and the air inside it is greater than the buoyant force acting on them, resulting in the balloon sinking.
Why does a balloon with argon sink?
A balloon filled with argon will sink because argon is denser than air. The density of a gas affects its buoyancy in the surrounding air; denser gases will sink while lighter gases will rise.
When an inflated balloon is exposed to cold air the volume of the balloon?
decreases. This is because the cold air causes the air molecules inside the balloon to move slower, reducing their kinetic energy and causing the balloon to shrink.

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 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
Why does a hot air balloon rise in cold air?
Hot air is less dense than cold air, so when the air inside the balloon is heated, it becomes lighter and therefore rises. As the balloon rises, the surrounding colder air cools it down again, causing it to sink if the heat source is turned off.
What determines if a balloon filled with a gas will rise or sink in the air?
A balloon filled with a gas will rise or sink depending on the density of the gas inside compared to the surrounding air. If the gas inside is less dense than the surrounding air, the balloon will rise. If the gas inside is more dense, the balloon will sink.
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 warm air rises cold air will what?
The cold air will sink.
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 come hot air balloons fly better in cold weather?
because the air inside the balloon has to be warmer than the air outside the balloon in order to fly higher, so if the air is warm it takes longer to fly higher so if you stop flying higher eventually the air will escape from the balloon making you sink which for obvius reasons is bad.
