By puting more hot air into it thus creating lift.
hot air rises cold air lowers, so when the hot air is traped it has no were else to go but up so it brings the hot air balloon with it.
And to decend a flap at the the top of the balloon opens by itsefl to let hot air out and to let you down.

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
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.
Why does heating the air in hot air balloon make it rise?
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
How do convection currents make a hot air balloon to rise?
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
Why would heating the gas in a hot air balloon make the balloon rise?
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
Will a balloon rise higher with hot air or cold air?
Hot air
Why does a balloon need hot air?
Hot air is less dense compared to cold air. The heated air in the balloon will rise, making the balloon float in the air.to make it rise.
How is a hot balloon lifted into the air?
to make a hot air balloon rise you use hot air
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
What would heating the gas in an air balloon make the balloon rise?
Simple...hot air rises..
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 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.
How do you make air lighter so that it will cause a balloon to rise?
To make air lighter you would increase the heat inside the balloon, making it less dense, causing it to rise.
Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?
He would heat it.
Why does heating the air in hot air balloon make it rise?
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
How does helium make a balloon rise when air doesn'?
Helium is lighter than air. So helium balloon rises in air.
Why can air balloon rise to the sky?
it can rise because of the helium and the gases help make it rise to the sky
