Why doesn't the hot air escape out of the bottom of a hot air balloon?

Because hot air rises, the warmest air in the balloon is at the top of it. As time passes the balloonist has to fire the burners to maintain the temperature of the air in the balloon, and to prevent it being squeezed put by the higher pressure of the cold air surrounding the balloon.

How does air escape from a balloon while it is tied?
The material of the balloon has pores- tiny holes too small to see without a microscope- but big enough to let air molecules slowly escape.
Why doesnt a balloon float with your air?
The air from your lungs has the same density as the air in our atmosphere. As a result a balloon inflated by a human using their lungs is unable to float.
Why do hot air balloons float in the air?
Hot air rises and the fire in the hot air balloon wants to go up and float in the air and since it's can't escape the balloon the fire just brings the balloon with it to float in the air
How does the air which is in a balloon escape from that balloon?
A balloon is stretchy. Therefore, when air is not being forced in, the ballon will try to contract to more or less of it's original size. When this happens, the air is forced out of a balloon until the molecular structure of the balloon is simillar to how it started out.
Why inflated balloon burst if press it hard?
An inflated balloon bursts if it is pressed hard because the molecules inside the balloon squeeze when it is pressed hard and air exerts pressure so the balloon bursts and let the air molecules escape from the balloon.
What is the word which means to let the air out of a balloon or tire?
Deflate is to allow air to escape from a balloon.
Why would heating the gas in a air balloon make the balloon rise?
Hot air rises more quickly than cold air, so when you heat the air inside the balloon, it cant escape, so it pushes the balloon up.
Why do you close the mouth of inflated balloon?
The air would escape through the mouth causing the balloon to DEflate

What will happen if you leave a balloon over night?
A small amount of air or helium within the balloon will escape through the balloon material.

Why does a hot air balloon when the air inside it is heated?
Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
