What uses convection?
Lava lamps and hot air balloons
How is convection used in hot air balloons?
Hot air rises because it occupies a greater volume per unit mass of air than cooler air, this makes it less dense. A hot air balloons fire generates hot air which floats inside the balloon, causing it to rise.
Which gas do you use for hot air balloons?
Hot air is used for hot air balloons.
What is convection used for?
Convection is a form of heat transfer. Convection is seen through the atmosphere and weather. It is also used in some appliances, such as convection ovens.
Why do balloons come closer when air is blown between them?
The wind between the balloons creates a lower pressure in the air, so the air around it pushes the balloons together.

Why do we use warm air in a hot air balloons?
This is because of convection. Hot air rises and cool air falls which causes the balloon to rise.
Explain why lighter-than air balloons fly?
"Lighter than air." Think about it for a second.
What is a hot air ballons air pressure?
The hot air balloons air pressure is usually used to explain the principle of buoyancy.
How is convection used in hot air balloons?
Hot air rises because it occupies a greater volume per unit mass of air than cooler air, this makes it less dense. A hot air balloons fire generates hot air which floats inside the balloon, causing it to rise.
Can hot air balloons get above the troposphere?
No because the air gets too cold for convection to happen, causing the hot air balloon to stay in place or even fall
Why lighter than air balloons fly?
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
Which gas do you use for hot air balloons?
Hot air is used for hot air balloons.
Explain the significance of hot air balloons to meteorologists?
Not much. While it's true that meteorologists do use balloons to send up weather probes, they tend to use gas balloons instead. It's simpler, cheaper and works better in their conditions.

What form is helium?
hot air balloons and balloons
Why do balloons come closer when air is blown between them?
The wind between the balloons creates a lower pressure in the air, so the air around it pushes the balloons together.
