# how does boyle’s law relate to hot air balloons

Boyle’s Law can be used to describe why a hot air balloon is able to keep such a large volume in the sky. As hot air balloons rise through the sky the pressure decreases, this allows the volume of the hot air balloon to increase. This being Boyle’s Law:less pressure means more volume.

## What is an example of Boyle’s Law in physics?

Usually in examples of Boyle’s law, our teachers mention hot air balloon, that the size of balloon increases as pressure decreases. But at as height increases pressure decreases because there are less molecules above us.

## What is Charles’law and how does it relate to balloons?

On the other hand, Charles’ Law holds that V ∝ T …and so if we enclose a volume of gas in a canopy, and give it a good blast with a gas burner the canopy inflates with hot gas…and will occupy a volume of air that MAY HAVE a greater mass than the mass of the balloon, the canopy, and the balloonists..and so the balloon floats…

## How does pressure affect the size of a balloon?

Usually in examples of Boyle’s law, our teachers mention hot air balloon, that the size of balloon increases as pressure decreases. But at as height increases pressure decreases because there are less molecules above us. How will the pressure of molecules outside the balloon effect the pressure of molecule inside the balloon.

## How does Charles’s Law affect the volume of a gas?

According to Charles’s Law, the volume of a gas has a direct relationship to the temperature of that gas. In the same way, a gas will expand as it is heated, such as when it is burned by a burner in a hot air balloon. What happens to the gas in a balloon when heated?

## How does pressure arise?

Like you said, pressure arises from the force exerted by the molecules on stuff. In case of the balloon whose pressure inside is higher than the pressure outside, the number of collisions per second of the molecules outside the balloon is lower than that of the ones inside. Thus the balloon feels a net force that is outward. So the balloon expands until the net force becomes zero. Thus happens when the rate of collision outside equals that of inside. This is nothing but the condition where the pressure is equalised.

## What is pressure in gas?

Pressure is force per area. Talking about gases, the pressure is said to be the force molecules exert on walls of let’s say a balloon.

## Why does pressure decrease when height increases?

But at as height increases pressure decreases because there are less molecules above us.

## Why does the balloon expand a bit?

So as the atmosphere gets thinner, the balloon expands a bit.

## What is Boyle’s law?

Boyle’s law is applicable for both internal and external pressure. Hence when external pressure decreases, the volume increases. The rubber then applies greater force to try to compensate for this loss of external pressure.

## What is the meaning of "back up"?

Making statements based on opinion; back them up with references or personal experience.

## How hot air balloon works Charles Law?

It all starts with the balloon. The giant balloon that is. It is this balloon that you will see tethered to the balloon basket which is hanging from the balloon’s tethers.

## What is the purpose of Charles Law?

A Charles Law is a law that is sometimes used to describe the balance between acceleration and the force on the airship. The law is often used in airship design.

## Who is Charles?

Charles Law (1726-1791), an English engineer and inventor, often referred to as ‘Charles Law of the Air’, was an English aeronautic engineer and balloonist.
