Air is pumped into a tire?
negative
Is there a limit to the amount of air that can be pumped into a bicycle tire?
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.
Is air in a tire a gas?
Yes, of course it is. It is usually ordinary air pumped into the tire under pressure.
Why does a tire get bigger as you pump it up?
Because, the air pressure hitting the tire, and as it hitting we put some air pressure into it so the tire is fully pumped up.
What type of air is pumped into a tire?
The kind you breathe, some pump Nitrogen into their tyres.
Tom plumped air into his bicycle tire until the tire is fullhe is still able to pump some air what does this show?
This shows air can be compressed so more air could be pumped in.
What happen when more air is pumped into the tire when temperature is kept constant?
The pressure goes up.
Will this entropy change by positive or negative air is pumped into a tire?
entropy is decreasing, so negative
Why does tire becomes warm when air is being pumped into it?
This could be caused by one or More of these factors. The Air Compressor that supplies the air heats the air before it gets to the tire. Feel the air to see if it is hotter. The air temperature rises as the pressure increases. So as you inflate the tire to raise the pressure, the temperature also rises.
How are the speeds of molecules of air affected when the air is compressed by the action of a tire pump?
When air is pumped into a tire at great speed, there is an increase in the temperature of the air. This is because the fast compressions cause the air molecules to move, whereas they remain still during a slow compression.
How much does a unicycle weigh?
That really depends on the size of the tire and air in it. An average 20" tire can easily hold 200lbs of weight so long as its not horrendously over pumped.
Additional air can be pump into the tire filled with air because?
The original air in the tire is old and weak so new air pumped in is stronger because it's newer and faster ;) Just kidding, really though the pressure of the air in the tire compared to the pressure of the air applied to the valve stem is the determining factor to whether or not you will be pumping air in the tire or letting it out of the tire. 10psi in the tire and 20psi at the air chuck equals a 10psi difference, and if the air chuck is applied to the valve stem the tire will fill with 10psi more of air and will then equal 20psi in the tire if the 20psi air pressure can be maintained at the fill chuck by an air compressor. Why, because different pressures will want to equal themselves to each other if they are aloud to occupy the same area with the higher pressure always wanting to expand into the lower pressure area, like inside a tire.
