When a balloon is blown up then let go air molecules rush out of the balloon and join the air molecules in the Earth's atmosphere What happens to the enthalpy in the balloon?
It decreases.
Why does a balloon float in air?
A balloon floats in the air when the molecules inside the balloon are less dense. The gas inside a helium balloon is in essence "lighter" than the air around it, causing a buoyancy effect which makes the balloon float. This can also be seen in hot air balloons when the air molecules are heated by the propane torch and excited, thus creating a less dense environment inside of the balloon compared to outside of the balloon.
What creates pressure?
Pressure inside of a balloon is created by the movement of the air molecules against the inner surface of the balloon. The more air inside the balloon, the more molecules that are hitting the same surface are, so there is more pressure.
What happens if there is too much air inside a balloon?
It too much air is added to a balloon it will burst.
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 happens to the air inside a balloon when you put it in a warm place?
The air inside expands.

It too much air is added to a balloon it will burst.

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 happens to a balloon if you keep blowing air into it?
the volume of air inside the balloon increases while the pressure of balloon decreases thus balloon inflates
What happens to a hot air balloon that allows it to float through the air?
Air inside the balloon is heated. Hot air is less dense than the surrounding air, and thus the balloon rises.
Why does a sealed gas balloon expand when it is brought from ground level to the top of a mountain?
the air is less dense at altitude, therefore it exerts less pressure. the gas in a sealed balloon will exert the same pressure regardless of it's altitude, so, with less outside pressure to overcome, the balloon will expand.
What happened when a balloon filled with air was squeezed and gently pressed?
The air inside the balloon is at a higher pressure than atmospheric pressure so the gas molecules inside the balloon are closer together on average than gas molecules outside the balloon. This means that the repulsive forces between the gas molecules inside the balloon are greater than the repulsive forces between the gas molecules outside it. When the balloon is opened, the gas molecules in the open end at the border between the higher pressure interior and lower pressure exterior will experience a greater repulsive force from the gas molecules inside the balloon than the molecules on the outside. This means that they experience a net force pushing them out of the balloon. As these gas molecules are pushed out by the gas inside the balloon, they push back on it with an equal and opposite force (due to Newton's 3rd Law of Motion). This equal and opposite reaction force causes the gas in the balloon to be pushed in the opposite direction to the escaping gas, which in turn pushes the balloon. As more and more gas escapes, the reaction force on the balloon continues to accelerate it, making it shoot off, until enough gas has escaped for the pressure inside the balloon to have dropped to the same level as the pressure outside the balloon.
What happens when air is blown into a balloon?
Air is transferred from your lungs into the balloon, where it diffuses inside the balloon and due to the elastic tendancies causes it to expand from the pressure of the increasing amount of air you blow in.
