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
It just does ;)
Convection. :)
hot air ballon because since the air is heated in the hot air balloon it will rise, And water boiling in a pan if you were cooking pasta you can see the pasta rise and fall with the convection current in the boiling water

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
Hot Air Rising And Cooler Air Falling Is One Example Of Convection Which That Example Is Called Convection Currents. Example Two An old-fashioned radiator creates a convection cell in a room by emitting warm air at the top and drawing in cool air at the bottom.

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