YES!!!

However, there is no need to heat the helium.

It is a light gas.

and it is an inert gas.

How does a balloon pilot control BOTH acsent and descent of a balloon?

Asked by Wiki User

A balloon pilot controls ascent by heating the air inside the balloon with a burner and descent by allowing the air to cool or venting it.

Why are hot air balloons so large?

Asked by Wiki User

The balloon skin must hold sufficient volume of lighter, hot air in order to pull the associated weight of the skin itself, the onboard gas cylinders and heating apparatus, any ropes which are needed to hold a dangling basket, the basket, counter-weights, passengers, supplies, and any other items of any weight up through the denser cold air outside it.

Heat makes for less dense molecule compaction because those molecules are moving in relation to the charge of energy they are holding. Less dense molecules rise above the more dense molecules which surround them. The pull of gravity on the ensemble must be overcome, so there must be sufficient volume within. Thus, a bigger balloon can lift more weight.

What is the gas that you use in balloons?

The gas commonly used in balloons is helium. It is lighter than air, which causes the balloon to float when it is filled with helium.

How and when have hot air balloons been used by the military?

Asked by Wiki User

Hot air balloons were first used by the military in the late 18th century during the French Revolutionary Wars. They were primarily used for reconnaissance purposes, allowing military commanders to gain a better view of enemy positions. The balloons were later used in the American Civil War for similar purposes, but their usage eventually declined with the advent of more advanced aerial technologies.

How can you make a hot air balloon fly?

Hot air balloons are made of lightweight manmade fabric cut from a pattern and sewn together on a sewing machine. A basket is suspended below it with a burner that heats the air on the inside. the basket is woven from rattan cane so that it will be as light as possible. Propane fuel is kept in containers in the basket to fuel the burner. It's pretty simple but a lot of work.

Where do you get big water balloons?

User Avatar

Asked by Wiki User

It depends where you buy them. . . but if you really want a bargain, go to the dollar stores and just buy a pack of them. I herd that the Family Tree sold them for $1.00 for 45 of them. . . so check around and then try to use rainwater instead or real water of get it from a lake to conserve water :)

At the end of a hot air balloon flight the heated air inside is allowed to escape through a panel that is opened either in the top or side of the balloon envelope. The crew then squeezes the remaining air our of the envelope and then packs it away in a large bag ready for the next flight. This process is called deflating the balloon
