Which best explains why a hot air balloon rises into the sky?
A hot air balloon rises into the sky because the air inside the balloon is heated, causing it to expand and become less dense than the cooler air outside. This difference in density creates buoyancy, allowing the balloon to float upward. According to Archimedes' principle, the upward force exerted on the balloon by the surrounding air is greater than the weight of the balloon, enabling it to ascend.
How does air make a balloon fly?
air is heavier than balloon, air rises
How does the air change as a hot air balloon rises?
As a hot air balloon rises, the air temperature typically decreases about 3.5°F for every 1,000 feet of altitude gained. This means the air in the balloon gets cooler as it ascends. Additionally, the pressure and density of the air decrease, causing the balloon to expand and rise higher.
What force makes a hot air balloon rise?
A hot air balloon rises due to the principle of buoyancy. As the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to float upwards. This effect is similar to how a helium balloon rises in the atmosphere.
What makes hot air balloon rise?
A hot air balloon rises because the air inside the envelope is heated by a burner, which makes it less dense than the surrounding cooler air. This lower density causes the balloon to float upwards, much like a cork in water.

What happens to the volume or size of a balloon as it rises in the air?
As a balloon rises in the air, the volume or size of the balloon increases. This is because the atmospheric pressure decreases as the balloon gains altitude, causing the air inside the balloon to expand and the balloon to inflate.
How does the air density inside a balloon change as it rises from the ground to the air?
The air density inside a balloon changes as it rises because the hot air inside the hot air balloon is less dense than the air around it causing it to fly since hot air rises. But as it rises it loses its hot air causing it to eventually not be able to fly anymore and come down.

What would heating the gas in an air balloon make the balloon rise?
Simple...hot air rises..
How do hot air balloons use air to fly?
Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.
Which gas law best explains why a hot-air balloon floats in the air?
The ideal gas law helps to explain why a hot-air balloon floats in the air. As the air inside the balloon is heated, it expands and becomes less dense than the surrounding air. This creates a buoyant force that allows the balloon to float.
Explain how a hot air balloon is lifted from the ground?
In a nutshell, air rises and expands when heated. Through the use of a burner the balloon pilot heats up the air inside the envelope (the balloon itself), this air inside the envelope expands and rises, lifing the basket.
