None. If it is fully inflated it will be full of air so there would be no room for any water.
If you mean a hot air balloon, it is the expansion of the air caused by the propane burner. If you mean any balloon, it is the ability of the material to hold the air or gas inside which keeps it inflated.
The rubber incasement the ball is made of as well as the composition of air withing when fully inflated causes a football to bounce.
Ok I dont know the answer but im stopping some wasteman saying "with air"
An inflated football is essentially more aerodynamic than a deflated football. The inflated one would travel faster and a greater distance. However, if you dropped them both at the same time, they would it the ground at the same time, because gravity pulls everything downward at 9.81 meters per second squared (ignoring the effects of air resistance in this last case).
To inflate something is to fill it with air. You can do that with an air pump, yes. Some things can be inflated without pumps, such as hot air balloons. And some pumps don't pump air.
The adjective 'pneumatic' means of or pertaining to air, gases, or wind; filled or inflated with air or gas.
no the football air can not seep out because of the low temperature and what the footballs made out of its perfectly made with pig and sowing
By football I am assuming American football. It is a rubber bladder with leather sewn around it and then inflated.
The type of air that keeps a beach ball inflated is kinetic energy.
A football used in a professional match within the UK should be inflated to 12.5 PSi exactly.
