You can see the flames in the photo at left.1. What happens when the air inside the balloon is heated

The balloon floats due to the difference in density

Explanation:

The air inside the balloon is warm as a result of it being heated. As warm air spreads out more, it has a lower density than cooler air.

A substance with a lower density rises over substances with higher densities as those sink lower. With the air in the balloon having a lower density, it will rise above the air outside which is colder and has a higher density.

the answer is a hope this
