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.
To make a hot air balloon go higher, the pilot will increase the temperature of the air inside the balloon by firing the burner. As the air inside the balloon becomes hotter and less dense than the surrounding air, it will create more lift, causing the balloon to rise. Adjusting the temperature and amount of hot air allows the pilot to control the balloon's altitude.
I think the hotter the fire is ( I'm not really sure on how to make fire hotter! :) sorry!) the higher the balloon goes. because hot air rises and so it seems right that if the air is hotter it will rise higher. if you are reading this answer then, you rock!!
To make a balloon rise in the air, one way is to fill it with a lighter-than-air gas, such as helium or hydrogen. The gas inside the balloon is less dense than the surrounding air, enabling it to float and rise. The amount of gas and the size of the balloon will determine how high it can rise.

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

A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
Simple...hot air rises..
There are many chemicals found in a hot air balloon to make it rise. The main elements/chemicals are Helium and Hydrogen.
He would heat it.

Helium is lighter than air. So helium balloon rises in air.
Heating the air in the balloon makes it less dense than the surrounding air, causing the balloon to become buoyant and rise. As the air inside the balloon cools, it becomes denser and the balloon descends. This process allows the pilot to control the altitude of the balloon.
it can rise because of the helium and the gases help make it rise to the sky
