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 air balloon come down after some time?
Hot-air balloons function on the principle that warm air rises, and the balloon mechanism holds onto hot air to ascend. Despite this, the hot air can't stay in the balloon forever, the opening at the top of the balloon allowing a slow and steady flow of the hot air out of the balloon and a gentle descent to the ground.
What is warm air draft fro a hot air balloon?
the warm is the fire
Why does the Hot air balloon rise when the fire is lit beneath the balloon?
The fire warms up the air and the air becomes less dense. So the balloon traps the warm air and since less dense gases rise with denser gasses around it, the warm air rises taking the balloon with it.
What do you think makes balloon stay up?
balloon stay up because of the air inside it. to make the balloon stay up the air should be light. inside the balloons you can find the air we called helium. helium is a light air that makes the balloon stay up. that's why if you blow the balloon it wont float because the air that comes from your mouth is not helium but carbon dioxide and carbon dioxide is heavier compared to helium so it wont float.
How does a burner flame cause a balloon to rise and stay aloft?
As the flame burns it heats the air around it making the air less dense than the cooler air above, the warm air particles rise to the top of the balloon and the balloon rises with the air. Essentially a hot air balloon uses a convection current to stay in the air.
What happens to the cooler air in the balloon when warm air enters the balloon?
it sinks

Warm air in a balloon will what?
EXPAND.
When a balloon is filled with air is heated does the density of the air in the balloon stay the same?
No it decreases
Why does the Hot air balloon rise when the fire is lit beneath the balloon?
The fire warms up the air and the air becomes less dense. So the balloon traps the warm air and since less dense gases rise with denser gasses around it, the warm air rises taking the balloon with it.
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 do you think makes balloon stay up?
balloon stay up because of the air inside it. to make the balloon stay up the air should be light. inside the balloons you can find the air we called helium. helium is a light air that makes the balloon stay up. that's why if you blow the balloon it wont float because the air that comes from your mouth is not helium but carbon dioxide and carbon dioxide is heavier compared to helium so it wont float.
Why does a hot air balloon when the air inside it is heated?
Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
How does warm air balloons float?
"Warm air", otherwise known as Hot Air Balloons, float because of one basic Law of Thermodynamics; heat rises. The air in a hot air balloon is hot, therefore, the balloon rises.
