the hot air from the heater rises forcing the cooler air out. this makes the balloon go up. this is convection

Yes, It is because in a hot air balloon the hot air rises and the cool air falls down.
Convection. :)
When the air inside a hot air ballon is heated the hot air rises, which makes the ballon rise hope i helped ;)

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.

how am i supposted to know
Convection.
Convection.
the hot air is more dense then the actual air
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
This is because of convection. Hot air rises and cool air falls which causes the balloon to rise.
