What do molecule do when you pump air into a bicycle tire?

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.

you need a sutible bicycle pump. you remove the cap on the tire, attach your pump and use the action on the pump. remove the pump air should not release and re attack cap ! :)

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.

Because I don't know what your teacher is looking for: At a pressure above atmospheric Compressed Confined

Usually the pump or compressor just takes air from the surrounding and pushes it into the tube/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.

This shows air can be compressed so more air could be pumped in.

Well, if the wheelbarrow tire has the kind of valve that'll work with the bicycle pump, just go ahead. Be aware that the wheelbarrow tire has a fairly large volume, so it'll most likely take you awhile to get it properly inflated.

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

Air goes in it the pressure increases and the tire becomes harder. If you keep pumping it'll eventually blow up.

Air fille bicycle tires were invented by John Dunlop.

If you force more stuff(=air)into an enclosed space, whatever that's in there becomes more closely packed. The more closely packed it becomes the higher the pressure gets. The pressure in a bicycle tire goes up as you pump air into it because the air is confined to a fixed volume. Therefore, as more air enters the air density increases, and at fixed temperatures, this will result in an increase in air pressure in the tire.

There is no gas in a tire pump, only air.

Well, you need a pump, or a compressor with the right type of nozzle for the type of valve you're using. Then, if you have a Presta valve, you need to know how to open it. Once you have that it's no problem inflating a bicycle tire.

It uses air to hold its shape and to support the bicycle. The compressive nature of the air allow a certain amount of tire material to give traction with the ground.

It's likely there's a rupture in the diaphragm that pulls the air into the chamber and then pushes it out to the valve. There are two "reed" valves in the pump that only allows the air to go in one direction with each valve. So when you pull up on the handle to fil the pump, one valve allows air in, but not out when you push down on the handle. Another valve at the bottom of the pump allows the air out when the handle is pushed down, going to the tire. There is another vavle on the tire that is opened only with the pumps adaptor, to allow air into the tire.

Most bike pumps are simple piston pumps. They consist of a piston or a plug that can be pushed through tube, a connecting rod, a handle and a tube. When the piston is almost pulled out of the tube there's an enclosed space in front of it, and as the handle is pushed in the air that's trapped ahead of the piston gets compressed and can be forced into a bicycle tire. Then as the handle is pulled out the design of the seal around the plug allows more air to be carried into the compression chamber while a valve by the tire prevents already compressed air from escaping backwards into the pump or the surrounding air. Answer Bicycle tire pump works just like any other simple force pump such as a bilge pump or lift pump. There is a valve blocking the flow of air out of the pump to the atmosphere while on the downstroke, and another valve stopping the flow of air from the tire to the pump cylinder during the upstroke. Tire pumps come in a huge variety of shapes and styles but this is one of the most common varieties. Some modern bicycle pumps deliver air on both the downstroke and the upstroke by having an additional set of valves. This reduces the time it takes to fill the tire. The air in the pump get compressed,and the pressure increases.

Pump air in it with a bicycle wheel pump

u pump air into an object such as a tire, or a ball.

A regular bicycle pump will just suck in ambient air8whatever air that's around it) before forcing it out through the nozzle.

ANY tire gauge measures air pressure in PSI.

Example: A bicycle tire pump uses mechanical energy (your body) and converts it into pneumatic energy (air out of the hose).
