How do hot air balloonists keep their balloons going?
Hot air balloonists keep their balloons going by constantly monitoring and adjusting the temperature of the air inside the balloon. By heating the air using a burner, the balloon can ascend, and by allowing the air to cool, the balloon can descend. By managing this process, the balloonist can control the altitude and direction of the balloon.
How do hot-air balloons fly?
Hot-air balloons fly by utilizing the principle of buoyancy. The heated air inside the balloon is less dense than the surrounding air, causing the balloon to rise. By controlling the temperature of the air inside the balloon, the pilot can ascend or descend as needed.
How does a hot air baloons fly?
Hot air balloons fly by heating the air within the balloon envelope, which causes it to become less dense than the surrounding air. This difference in density creates lift, allowing the balloon to rise. By controlling the temperature of the air inside the balloon, the pilot can make the balloon ascend or descend.
How are hot air balloons work?
Hot air balloons work by heating the air inside the balloon with a burner, which causes the balloon to become buoyant and lift off the ground. The hot air inside the balloon is lighter than the cooler air outside, creating a pressure difference that allows the balloon to float. By controlling the temperature of the air inside the balloon, the pilot can ascend or descend to navigate the balloon.
How does a hot air balloon go down?
A hot air balloon can descend by either releasing hot air from the balloon envelope or by opening a vent at the top of the balloon to allow some of the hot air to escape. This reduces the buoyant force that is keeping the balloon in the air, causing it to descend slowly. The pilot can control the descent rate by carefully managing the release of hot air.
What forces are used ina hot air balloon?
Hot air balloons use the force of gravity to descend and the force of buoyancy to ascend. The buoyant force is created by heating the air inside the balloon, making it less dense than the surrounding colder air. The air pressure inside the balloon also plays a role in controlling the altitude of the balloon.
How does convection apply to a hot air balloon?
In a hot air balloon, convection is the process of hot air rising due to its lower density compared to the cooler air around it. The burner at the base of the balloon heats the air inside the balloon, causing it to become less dense and rise. As the air cools at higher altitudes, the balloon gradually descends. This cycle of heating and cooling allows the balloon to ascend and descend by controlling the temperature of the air inside.
How does a hot-air balloon rise?
A hot-air balloon rises because the air inside the balloon is heated, which makes it less dense than the surrounding cooler air. This creates a buoyant force that lifts the balloon. By controlling the temperature of the air inside the balloon, the pilot can ascend or descend.
Why does a change in density of the air make the balloon ascend?
When the air inside the balloon is less dense than the surrounding air, it creates lift force due to the pressure difference. This difference causes the balloon to ascend because it is buoyant in the less dense air.
What gas is used for a hot airballoon?
I am fairly sure that hot air balloons use normal air. They rely more on the idea of bouyancy rather than using specal gases, such as helium. The hot air inside of the balloon is more bouyant than the cold air outside of the balloon. So that makes the balloon ascend till the temperature of the air inside of the balloon is equal to the temperature of the air outside of the balloon. Then as the air inside the balloon gets colder, the balloon starts to descend.
How do hot air balloonists keep their balloons going?
Hot air balloonists keep their balloons going by constantly monitoring and adjusting the temperature of the air inside the balloon. By heating the air using a burner, the balloon can ascend, and by allowing the air to cool, the balloon can descend. By managing this process, the balloonist can control the altitude and direction of the balloon.
How is the descend and the ascend of a submarine controlled?
By pumping water or air into the ballast tanks.

How do hot air balloons descend?
Hot air balloons descend by releasing hot air from the balloon envelope, causing it to cool down and become denser. This decrease in density causes the balloon to descend slowly until it reaches the ground. Pilots control the rate of descent by manipulating the amount of heat in the balloon.
