We know from the ideal gas laws that when you heat a gas under constant pressure, it will expand. (In a hot air balloon, the air that is heated is not in a rigid container, but in a balloon that expands with the expanding gas; the pressure it is under is only the atmospheric pressure.) The expanded gas will then have a lower density and will therefore be bouyant in air, and therefore able to lift a balloon.
What else can I help you with?
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.
What does it mean when a balloon floats to you?
When a balloon floats towards you, it means that the air inside the balloon is less dense than the air surrounding it, causing it to rise and move in your direction.
Why does a balloon float in the air?
It floats in the air because of the helium inside. Helium's density is less than that of oxygen, same reason fat floats in water.
What object represents air?
An air balloon or a feather can be used to represent air. The balloon is filled with air and floats, while the feather is light and gets easily carried by the air.
Why does an air balloon not float?
A hot air balloon floats because the air inside is heated, making it less dense than the cooler air outside. This creates a buoyant force that lifts the balloon. If the air inside the balloon is not heated, it will not be less dense than the surrounding air, and the balloon will not float.

What floats in air?
A balloon.
What does it mean when a balloon floats to you?
When a balloon floats towards you, it means that the air inside the balloon is less dense than the air surrounding it, causing it to rise and move in your direction.
How a hot air balloon rises?
The hot air is less dense than the air surrounding the balloon, so it floats in the surrounding air.
Why a hot air balloon floats?
A hot air balloon floats because the air inside the balloon is heated, making it less dense than the cooler air outside. This difference in density creates a lifting force called buoyancy, allowing the balloon to rise in the atmosphere.
Why is that a big balloon filled with the helium floats?
Helium is lighter than air. hence helium balloon will float in air.
Why does a balloon float in the air?
It floats in the air because of the helium inside. Helium's density is less than that of oxygen, same reason fat floats in water.
Does a hot air balloon float or fly?
A hot air balloon floats in the air because it is buoyant due to the hot air inside the balloon being lighter than the cooler air outside. It is not propelled by engines or wings like an airplane, so it is more accurate to say it floats rather than flies.
Why a balloon filled with helium floats in air?
Helium is less dense than air
What floats on air?
helium balloon because helium is less dense than air
If a balloon filled with an unknown gas floats in the air then what can be said about the gas in the balloon?
The gas in the balloon is lighter than air. It has a specific gravity relative to air of less tha one.
What is a man made device that floats on air because the air inside if it is heated?
Hot air balloon.
