Hot air. That's what makes it float.

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 is it better to launch a hot air balloon on a cold day?

it is better ot launch a hot air balloon on a cold day than on a warm day because the air rises in the atmosphere therefore if you were to go for a cold day you would go very high but if you were to go a ride on a hot day the hot air balloon wont go as high as on the cold day .


Why is cold temperature the best to fly a hot air balloon in?

Cold temperature is ideal for flying a hot air balloon because it allows for better lifting capacity due to the denser, cooler air. The temperature difference between the air inside the balloon and outside helps to create buoyancy and lift the balloon. Cold air also allows for more control over the altitude and direction of the balloon during the flight.


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.


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.


Why does a balloon sink in cold air?

A balloon sinks in cold air because the air inside the balloon cools down, causing it to contract and become denser. This increased density makes the balloon heavier than the surrounding air, causing it to sink.


When an inflated balloon is exposed to cold air?

The volume of the balloon decreases


When an air balloon decreases in cold air does the density of the air in the balloon decrease?

Yes, the density of the air in the balloon decreases when it is in colder air. This is because cold air is more dense than hot air, so as the air balloon cools down, the air molecules become more closely packed together, leading to an increase in density within the balloon.


Does cold air expand inside a balloon?

Yes, cold air contracts and takes up less space, causing the balloon to deflate.


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.


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

Hot air
