When the air inside a hot air balloon is heated, it expands and takes up a larger volume. as a result, it floats higher into the sky. what else happens to the air inside the balloon as it is heated?

I believe it becomes gasses the hotter it gets

ABC. Heating air under the balloon will cause the air inside to expand.

The air inside will have the same mass but more volume.

Heating the air under the balloon will cause the entire balloon to rise.

Explanation:

Scientists use curiosity, imagination, and previous scientific study to create research questions and hypotheses to begin their investigations into natural phenomenon. They use this process which formally is called the scientific method to carefully construct experiments to guide investigations of the world around them. Hope this helps!!
