it slowly leaks out of the balloon, to equalize oxygen and Co2 levels.
the volume of air inside the balloon increases while the pressure of balloon decreases thus balloon inflates
It too much air is added to a balloon it will burst.
The air warms and expands, becoming lighter than the surrounding air, thus lifting the balloon.
It decreases.
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.
it sinks
The balloon expands.
the volume of air inside the balloon increases while the pressure of balloon decreases thus balloon inflates
It too much air is added to a balloon it will burst.
Air inside the balloon is heated. Hot air is less dense than the surrounding air, and thus the balloon rises.
the air pressure outside of the balloon decreases.
A hot air balloon would not work on the moon.
It will fill the balloon and make a oval sphere.
The air warms and expands, becoming lighter than the surrounding air, thus lifting the balloon.
it pops
It decreases.
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.
