because warm gases rise because they are less dense than normal air, so the hot air from the flame is trapped in the balloon thus lifting it off the ground.

When the balloon is floating high above the ground how could the balloonist make the balloon descend gradually?

the balloonist would turn off the burner, allowing the air inside the balloon to cool down. Hot air rises so as the air cools down the balloon will lose altitude.


How does a hot air balloon work?

Hot air balloons get their buoyancy from hot air created by a propane burner at the base of the balloon. Hot air is less dense than cold air and so weighs less. When the cold air that is displaced weighs more than the balloon, the balloon will rise. The balloons weight is controlled by turning the burner on and off when needed. The hot air is less dense than the outside air and so the balloon is squeezed upwards by the surrounding air. The air becomes less dense as more heat is applied, particles separate more and more when heat is applied. The more heat is applied the further apart and less dense the particles become.


What are some applications for Charles law?

Hot air balloons are an ingenious application of basic scientific principles. Here we will show exactly how the balloon works, what makes it rise and fall and how a pilot is able to maneuver it when it is in the air.The basis of how the balloon works is that warmer air rises in cooler air. This is because hot air is lighter than cool air as it has less mass per unit of volume. Mass can be defined by the measure of how much matter something contains. The actual balloon (called an envelope) has to be so large as it takes such a large amount of heated air to lift it off the ground. For example, to lift 1000 pounds worth of weight you would need almost 65,000 cubic feet of heated air! To help keep the balloon in the air and rising, hot air needs to be propelled upwards into the envelope using the burner (see separate section on burners for more information.)A hot air balloon is made up of 3 main parts:The EnvelopeThe actual fabric balloon which holds the airThe BurnerThe unit which propels the heat up inside the envelopeThe BasketWhere the passengers and pilot standThe burner uses propane gas to heat up the air in the envelope to move the balloon off the ground and into the air. The pilot must keep firing the burner at regular intervals throughout the flight to ensure that the balloon continues to be stable. Naturally, the hot air will not escape from the hole at the very bottom of the envelope as firstly, hot air rises and secondly, the buoyancy keeps it moving up.The controls for piloting a balloon are actually extremely simple....1 - To move the balloon upwards - the pilot opens up the propane valve which lets the propane flow to the burner which in turn fires the flame up into the envelope. Works in much the same way as a gas grill, the more you open the valve, the bigger the flame to heat the air, the faster the balloon rises.2 - To move the balloon downwards - the 'Parachute Valve' at the very top of the balloon is what is used to bring the balloon down towards the ground. It is essentially a circle of fabric cut out of the top of the envelope which is controlled by a long chord which runs down through the middle of the envelope to the basket. If the pilot wants to bring the balloon down he simply pulls on the chord which will open the valve, letting hot air escape, decreasing the inner air temperature. This cooling of air causes the balloon to slow its ascent.So essentially this takes care of the up and down movement, so how does the balloon move from place to place? Again the answer is very simple, the pilot can maneuver horizontally by changing the vertical position of the balloon because the wind blows in different directions at different altitudes. If the pilot wants to move in a particular direction they simply ascend and descend to the appropriate level and ride with the wind.BY: John Michael Manga-o19-


Why does hot water blow up a balloon?

Hot water blows up a balloon because it is taking up space. Second, Hot water gives off extra gas to fill up a balloon quicker.


How do air particles create air pressure inside a balloon?

Because the partials are pudding off the balloon it us making it bigger

How do you get off a hot air balloon?

You climb out when the balloon lands on the ground and the basket is secure.


What make a hotair balloon go up?

Hot air goes into the balloon. sense the air is so hot, it pushes the balloon off the ground and floats in the air!


Why does the heating of gas cause a hot air balloon to rise?

Because hot air rises and a hot air balloon utilizes this. As the hot air rises it lifts the balloon so that it lifts off from the ground. And the reason why the hot air balloon has a burner, the thing that is connected to the balloon itself and shoots flame into it, is because the hot air inside the balloon begins to cool causing it to fall so the burner reheats the air so that it doesn't return back to the ground.


What gas do we fill in hot air balloon?

Hot air balloons are filled with hot air from a propane burner in the basket. Hot air rises. So provided the cooling air in the balloon is topped up from short blasts from the burner, the balloon will rise off the ground.

Why does a hot air balloon need flame in order to take off?

A Balloon needs hot air to rise, the flame, which is gas burning, heats up the air in the balloon. As Hot air rises above cooler air the balloon takes off.


How do air balloons lift off from the ground?

Balloons filled with Helium rise because Helium is less dense than normal air. Hot air balloons lift off the ground because heat rises, and when the balloon is full of air of a higher temperature than its surroundings, the balloon will rise.


Why does a hot air balloon need a burner to work?

To keep it hot you. The REASON they use a 'Burner' in a Hot Air Balloon is to 'heat the Air, to 'fill' the Balloon, so it will 'rise'... The only other way to get the air Hot enough to fill the Balloon, would be to make the 'Basket' MUCH, MUCH Larger, and fill it with Liberals, and just let them talk. BUT, I don't think the Balloon would ever get off the ground, because, the BULLCRAP would counteract the Hot Air, and they would cancel each other out...

Does a hot air balloon drop you off where it picks you up?

no


Why does a gas burner in a balloon begin to rise when heated air is trappd inside the balloon?

The hot air from the gas burner rises and enters the balloon's envelope. Once there is enough hot air trapped, the whole balloon will begin to lift off the floor. This is due entirely to the fact that hot air rises.


Why does an air balloon float?

If you mean hot air balloon then it floats because hot air rises because it is less dense and with enough hot air caught in the balloon it can lift create enough lift to take off into the air. If you mean a helium balloon then it rises because helium in the balloon is less dense then the air around it. Since less dense things rise to the top the balloon will float.
