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 decreases.
It goes up because you are adding air to it which also has weight.
The balloons shape changed and went through an outward distortion. The volume of the balloon expanded as air was blown into it.
if you think about it, air molecules increase more and more. And the balloon has it flexibility. But the balloon can only stretch out a far distance. Henceforth, too much air molecules from you will make the balloon pop
The pressure inside is greater than outside, or else the balloon would not blown up.

A blown up balloon is weightless because the whole thing is just air and air has no weight

Air, or oxygen and nitrogen is matter. All matter has mass. So the answer to this question is yes, air in a blown up balloon or any air does have mass.
The balloons shape changed and went through an outward distortion. The volume of the balloon expanded as air was blown into it.
it sinks
A hot air balloon can stay in the air because the hot air is less dense than cool air. The hot air that is blown into the balloon causes it to rise and a burner is used to heat the air inside of the balloon to keep it floating.
if you think about it, air molecules increase more and more. And the balloon has it flexibility. But the balloon can only stretch out a far distance. Henceforth, too much air molecules from you will make the balloon pop
When the air inside a balloon cools, it will also contract, therefore the balloon will partially deflate.
The pressure inside is greater than outside, or else the balloon would not blown up.
The balloon expands.
