because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.

When does a hot air balloon rise?
When a hot air balloon is filled with the hot air the air around the balloon is a lot denser. So by convection the balloon rises and the less dense air is replaced by dense air underneath it.
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.
The air in hot air balloon is heated to make the balloon rise?
The volume of air increases on its heating hence the balloon rises on heating
Why will increasing the temperature in a hot air balloon make it rise faster?
Balloon is too roasting to be hot. Balloon is so much more blazing
How do you make a balloon rise into the air?
-- Inflate the balloon with some substance that is less dense than air. OR -- Inflate the balloon with air, then heat it after it is sealed.
What chemicals from the periodic table make a hot air balloon rise?
There are many chemicals found in a hot air balloon to make it rise. The main elements/chemicals are Helium and Hydrogen.
How do lithosphere plates move where convection currents rise?
They move apart.
What are convection currents in earths mantle?
the heat makes it rise up
Where can a divergent boundary occur?
They occur when the convection currents are less dense and rise.
How do convection currents contribute to eutrophication?
Some of the substances that give rise to eutrophication in a system naturally settle to the bottom. However, convection currents can bring them closer to the surface again.
What property of hot air causes it to rise and help create convection currents?
Density.
What kind of heat transfer causes a hot air balloon to rise?
Convection.
Describe the convection currents that occur inside Earth?
Convection currents are the movement of fluid as a result of differential heating or convection. In the case of the Earth, convection currents refer to the motion of molten rock in the mantle as radioactive decay heats up magma, causing it to rise and driving the global scale flow of magma.
Does mantle material rise in convection currents because heated materials become more dense?
no
What are effects of connection currents in the mantle?
The flow of mantle effects convection currents in the mantle. This process happens as hot material within the mantle begins to rise. As it rises, it begins to cool and then sinks. This process repeats as a cycle of convection currents.
How do convection currents affect the lithosphere?
Convection currents in the asthenosphere helps form subduction zones at convergent boundaries and ridges at divergent boundaries. This slow and continuous convection causes the plates on earth's crust to move.
What will happen to the convection currents in the mantle if earth's interior cools down?
Convection currents are transferring heat to the surface through the movement of mantle rock. If the interior of the planet cools, the mantle rock would be too solid to move, and there would be no heat to transfer.
