Why did they call it the hot air balloon?
The name "hot air balloon" comes from the fact that hot air is used to make the balloon rise. The balloon is inflated with heated air, which is less dense than the cool air surrounding it, causing the balloon to lift off the ground.
Why does a hot air balloon rise when the air inside it is heated?
When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air. This density difference creates a buoyant force, causing the balloon to rise. As long as the air inside the balloon is heated, it will continue to rise.
When is the density of a hot air balloon the greatest?
The density of a hot air balloon is the greatest when the air inside the balloon is at its maximum temperature. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, causing the balloon to rise.
Why the hot air balloon needs hot air to make it rise?
Hot air is less dense than cold air, which makes it more buoyant. When the air inside the balloon is heated, it becomes lighter than the surrounding air, causing the balloon to rise. This is due to the principle of buoyancy, where objects with lower density than the fluid they are in will float or rise.
What is the name of the gas that is filled in hot air balloons to make them soar and rise up in the sky?
The gas filled in hot air balloons to make them rise is called propane or natural gas. It is heated to create a lighter-than-air gas that provides lift to the balloon.
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.

When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air. This density difference creates a buoyant force, causing the balloon to rise. As long as the air inside the balloon is heated, it will continue to rise.
How does the balloon get heated up?
A balloon gets heated up by the sun or another external heat source that warms the air inside the balloon. The heated air inside the balloon becomes less dense than the surrounding air, causing the balloon to rise.
What happens to a destiny when the balloon is heated and the volume doubles?
When a balloon is heated and its volume doubles, the density of the air inside the balloon decreases. This change in density causes the balloon to rise since it becomes less dense than the surrounding air. The balloon will continue to rise until the internal air reaches equilibrium with the external air.
When is the density of a hot air balloon the greatest?
The density of a hot air balloon is the greatest when the air inside the balloon is at its maximum temperature. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, causing the balloon to rise.

Why is an hot air balloon called a hot air balloon?
A hot air balloon is called such because it is filled with hot air to make it rise. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to float upwards.
How is particles used in hot air balloon?
In a hot air balloon, the particles refer to the air molecules inside the balloon that are heated by the burner. When the air molecules are heated, they become less dense and rise, creating lift for the balloon. This process allows the hot air balloon to float in the cooler, denser air around it.
Why does heating the air in hot air balloon make it rise?
Heating the air inside the balloon makes it less dense and lighter than the surrounding cool air, causing the balloon to rise. As the air inside the balloon expands and becomes less dense, it creates lift because it is now buoyant in the cooler, denser air.
How does thermal expansion make a hot-air balloon rise?
It rises because when thermal engery is in the balloon it makes an expansion that makes the balloon fly
