A hot air balloon ascends and descends by controlling the temperature of the air inside its envelope. To rise, the pilot heats the air using a burner, making it less dense than the cooler air outside, which creates lift. To descend, the pilot allows the air to cool or releases some air through a vent at the top of the envelope, increasing the density and causing the balloon to sink. This careful management of air temperature enables precise altitude control during flight.
A hot air balloon goes up when the air inside the balloon is heated, causing it to become less dense than the surrounding air. This creates lift. To descend, the air inside the balloon is allowed to cool, increasing its density, which causes the balloon to lower.
When the hot air in a balloon cools down, it becomes denser and contracts. This causes the volume of the balloon to decrease, resulting in a decrease in buoyancy and making the balloon start to descend. The rate of descent will depend on factors such as the rate of cooling and the weight of the balloon.
A hot air balloon floats because the air inside the balloon is heated, making it less dense than the cooler air outside. This difference in density creates a lifting force called buoyancy, allowing the balloon to rise in the atmosphere.
There is a flap in the top of the balloon that you open to let the hot air out and the balloon gets lower. Or, you can just wait a little bit, the air cools down, and it goes down, all by itself!
Altitude is controlled by the propane burner and the parachute valve. The parachute valve is an opening at the top of the balloon envelope. When closed, it traps hot air from the burner inside the balloon, making the hot air balloon rise. When opened, it allows hot air to escape, and the hot air balloon descends. The reason a hot air ballon rises is because the density of the balloon is less than the density of the surrounding air. Its the same thing as "why does a boat float". In the case of the balloon, the operator modulates the flame on and off to maintain the desired altitude - increase the flame, and the balloon goes up - decrease or shut off the flame, and the balloon goes down. A better metaphor to a boat is a submarine - add ballast and the submarine goes down - blow ballast and the submarine goes up.
The heated air causes the whole balloon to rise. When the air inside the balloon cools down, or when the hot air is let out, the balloon goes down.
what goes up, goes down!
A hot air balloon goes up because the hot air inside is less dense than the surrounding air. Therefore, the hot air rises, bringing the balloon up with it.

In a hot air balloon, a gas burner is used to heat air to a temperature of about 212°F (100°C). Since hot air is lighter and less dense than the cool air around the balloon, the heated air causes the whole balloon to rise. When the air inside the balloon cools down, or when the hot air is let out, the balloon goes down. A hot air balloon is powered by hot air, hot air is lighter (less dense) then the air outside of the balloon (More dense) Heat rises, so the heated air, pushes up into the balloon allowing the balloon to lift. The more heat, the faster it will go, the less heat, the slower it will go, until it starts to descend. Decent is relatively slow, because the air is slowly cooling, however the cooler the air the faster the decent is. To avoid rapid falling, heat it applied to reheat the air so the decent goes slowly.
bust the balloon
A hot air balloon goes up because the air inside the balloon is heated, which makes it less dense than the surrounding cooler air. This creates a buoyant force that causes the balloon to rise. The pilot controls the altitude by adjusting the temperature of the air inside the balloon.
