There is hot air to make it fly and there are weights to stear it.
To go up. "The hot air balloon ascended in the morning sky."
Well it has a gas fueled flame and the flames heat makes the balloon part fill up with hot air. Hot air rises so the hot air balloon will float into the sky like a helium balloon would.
Hot air has density less than the air surrounding the balloon. When the average density of the balloon filled with hot air is less than the density of the air outside upthrust is more than the weight of the balloon. therefore it keeps on rising up till the upthrust becomes equal to the weight of the balloon.
In a "hot air" balloon, which you refer to in your question, the gas is hot air. Heated air rises, so the balloon rises. The gas used in the burner, to heat the air, is propane.
Sky lanterns are a small hot air balloon which is made of paper. In Asia they are commonly used for festivities. In China however they were used in wars.

a hot air balloon works when the hot air blowing from the bottom pushes up the balloon which lifts it up into the sky where it moves in the direction where the wind blows .

There is a candle at the bottom of the lantern. the candle will then be lighted and hot air rises, which makes the lantern fly. its the same logic as a hot air balloon
To the sky,of course.
Due to the weight of the balloon. A balloon is merely a capsule full of air so it will fall to the ground as the balloon weighs it down. A helium balloon will rise into the air because helium is less dense than normal air (i.e. it weighs less). The air inside the balloon is the same density as the air outside. The balloon material itself is heavier than air, which causes the balloon to sink. If you decrease the density of the trapped air, such as by heating it or replacing it with hydrogen or helium, the balloon may become even lighter than the balloon material and an equal volume of normal air, in which case the balloon will float or rise.
it can rise because of the helium and the gases help make it rise to the sky
It falls out of the sky and you die
In a hot air balloon high in the sky
Because air is not as dense as helium filed gallons so they won't float
half so high in the sky
Hot air has density less than the air surrounding the balloon. When the average density of the balloon filled with hot air is less than the density of the air outside upthrust is more than the weight of the balloon. therefore it keeps on rising up till the upthrust becomes equal to the weight of the balloon.
