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.

How a hot air balloon is lifted from the ground?
A hot air balloon is lifted from the ground by heating the air inside the balloon with a burner. As the air inside the balloon heats up, it becomes less dense than the surrounding air, causing the balloon to rise. The pilot can control the ascent and descent of the balloon by adjusting the temperature of the air inside.
How does the temperature effect the balloon filled with air?
As temperature increases, the air molecules inside the balloon also heat up, causing them to move faster and exert more pressure on the walls of the balloon. This can cause the balloon to expand. Conversely, a decrease in temperature will cause the air molecules to slow down, resulting in a decrease in pressure and the balloon to shrink.
Why does balloon filled with air shrink when placed in the cold dry ice container?
When the balloon is placed in the cold dry ice container, the air inside the balloon cools down, causing its temperature to decrease. As a result, the air molecules lose energy and move slower, leading to a decrease in pressure and volume inside the balloon, causing it to shrink.
If you place a balloon filled with air into the refriferator the balloon will get smaller.The balloon undergoes what?
The balloon undergoes a decrease in temperature, causing the air molecules inside it to lose energy and move closer together. This results in a decrease in pressure and volume, causing the balloon to shrink in size.
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 does a balloon blown up with cold air falls o the ground but one balloon blown up with helium floats upward?
Helium is lighter than air so it floats. Cold air is fairly "heavy'" so it sinks to the bottom Average density of air + baloon is greater than surrounding air so it falls to highest density option ie downwards.
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
What is the crystalline water that falls out of the cold atmosphere?
The crystalline water that falls out of the cold atmosphere is known as snow. Snow forms when water vapor in the atmosphere freezes into ice crystals and then falls to the ground.
How does the temperature effect the balloon filled with air?

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 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.
What happens to a balloon when it is submerged in cold water?
When a balloon is submerged in cold water, the air inside the balloon cools and contracts, leading to a decrease in volume. This causes the balloon to shrink in size.
If you take a helium balloon from inside a warm house to outside on a snowy day what will happen to the balloon could you classify this as a phase change?
As the warmer air inside the balloon cools, the balloon will shrink slightly. The amount of shrinkage will depend on the temperature change.
When an inflated balloon is exposed to cold air?
The volume of the balloon decreases
