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.
Can you make a balloon that float in air?
Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.
How do helium balloons float in the air?
Helium balloons float in the air because helium is lighter than the surrounding air. This causes the balloon to be buoyant and rise upwards.
What must happen for a balloon to float in the air?
For a balloon to float in the air, it must be filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
How does heilum make a balloon float?
When helium is added to a balloon, it decreases the overall density of the balloon compared to the surrounding air. This causes the balloon to float because the buoyant force exerted by the helium is greater than the force of gravity acting on the balloon. This buoyant force allows the balloon to rise in the air.

If you wanted to make a balloon float in the air which gas should you use to fill the balloon?
Helium gas is lighter than air and hence balloons filled with helium will float in air.

What happen when a balloon is filled with helium?
When a balloon is filled with helium, it becomes buoyant because helium is lighter than the surrounding air. This causes the balloon to rise and float. The helium gas inside the balloon also increases the pressure, which helps the balloon maintain its shape and stay inflated.
Why do helium balloons float?
Helium balloons float because helium gas is lighter than the surrounding air. This causes the balloon to be buoyant and rise up in the atmosphere.
What happens to the weigh to balloon when it is blown up and why?
When a balloon is blown up, it becomes lighter because the air inside the balloon is less dense than the surrounding air. This causes the balloon to float or rise upward, due to the principle of buoyancy.
Why are hot air balloons able to rise into the air?
Hot air balloons rise because when the air inside the balloon is heated, it becomes less dense than the surrounding cooler air. This difference in density creates lift, causing the hot air balloon to float upward.
How does a hot air balloon rise in the sky?
A hot air balloon rises in the sky because the air inside the balloon is heated, making it less dense than the surrounding air. This causes the balloon to float upwards, as the less dense hot air inside the balloon is lifted by the denser, cooler air outside.
Why the hot air balloon needs hot air to make it rise?
Hot air balloons use hot air because hot air rises above cold air. The air inside the balloon is heated above the temperature of the air outside the balloon. The warmer air trapped inside the balloon then causes the balloon to float above the outside colder air.
