Question

If you add air to a flat tire through a single small entry hole, why does the air spread out to fill the tire

Answer 1

the tire fills up just like any thing else that holds air when u pump a ball or tire up it fills all the way up cause it is a small confined space and after filling it with air the atoms of the air fill the tire up

Answer 2

Step-by-step explanation:

Air is made up of small particles which occupies all the place if filled in a close body.

A flat tire has a small nozzle to fill in air. As air pumped into it, it tends to spread itself into the complete tube.

This air gives shape to the rube making it perfectly circular. The particles of air have a greater inter molecular spacing and can acquire any shape.

This air given to the tire spread out in every part.
