∙ 12y agoair with an air pump
A Bicycle Pump is used to pump the tyres on Bikes it is normally a simple hand operated device which pushes air through a tube atached to a nozel which is screwed to the Valve on a Bicycle inatube the air is then forced into the Bicycle Tire.
Air is put in with a pump or a compressor, either way it becomes pressurised to inflate the tire.
If the pump, valve, and tube are OK - yes.
When air is pumped into a bicycle tire, the molecules in the air are pushed into the tire, increasing the pressure inside. The molecules move more rapidly and collide frequently with the walls of the tire, which causes the pressure to rise. This increased pressure creates a force that keeps the tire inflated and able to support the weight of the bicycle and rider.
Usually the pump or compressor just takes air from the surrounding and pushes it into the tube/tire.
This shows air can be compressed so more air could be pumped in.
Yes there most certainty is a limit to the amount of air that can be pumped into a bicycle tire. Put too much air in the tire and it will explode. The maximum air pressure for the tire is listed on the sidewall of the tire.
how much air is in the tire
Because air, fluffy as it is, is still "stuff", and all stuff has weight. When you pump a tire you're putting more stuff into it, so the weight do go up.
Air goes in it the pressure increases and the tire becomes harder. If you keep pumping it'll eventually blow up.
When you are not sitting on it.
