It is an air-balloon which can be steered in the air.
It's called the "mouthpiece" of a balloon, where you blow air into to inflate it.
A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.

A hot air balloon lifts a basket of people by heating the air inside the balloon with a burner. As the air inside the balloon becomes warmer, it becomes less dense than the cooler air outside. This temperature difference causes the balloon to rise, carrying the basket and passengers with it.

The hot air balloon was made for people to travel in the air.
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
Just the density difference between the balloon and surrounding atmosphere is so great that the balloon is able to lift itself and people.
