How is particles used in hot air balloon?

Why does an unopened bag of potato chips left in a hot car appears to become larger?
Air Expands When Heated
How does air density inside a hot air balloon change as the air is heated?
As the air inside a hot air balloon is heated, its density decreases because the air molecules expand and spread out, becoming less concentrated. This decrease in density causes the balloon to become less dense than the surrounding air, allowing it to rise.
Is hot air balloon one word?
No, "hot air balloon" is typically written as three separate words. It refers to a type of aircraft that uses heated air to become buoyant and ascend in the atmosphere. When used as an adjective, it can sometimes appear hyphenated, as in "hot-air balloon."

Does the air in a hot air balloon increase or decrease its density?
The air in a hot air balloon decreases in density when it is heated. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, creating lift.
How does the air inside a hot air balloon help it to become light and float in the sky?
The air inside a hot air balloon is heated by a burner, which makes it less dense than the surrounding cooler air. This difference in density creates lift, allowing the balloon to float in the sky.
What are hot air balloons filled with?
It is simply air that has been heated. Hence the namehot air balloons are filled with hot air from a propane tank
What does cold air have more than hot air?
Cold air is more dense than hot air. This is because gas expands when it is heated.
Is a hot air balloon rising a chemical change?
No, a hot air balloon rising is a physical change, not a chemical change. The balloon rises because the air inside it is heated, causing it to expand and become less dense than the surrounding air, which causes it to float upwards.
