What happens to air when after repeated compression and expansion?

Nothing much. Compression heats it up, expansion cools it down. Unless the machine that does the compressing and expanding add something, it'll stay exactly the same.

What is thunder and how does it occur?
Thunder is a sound made by lightning, where the sudden increase in pressure and heat from the lightning causes a rapid expansion of air that resulted in a loud sound.
How do you get combustion?
Any combustion needs Fuel, Oxygen and heat. In a petrol engine, the fuel and air are mixed in either a carburettor, or a fuel injector system. The heat is supplied by the spark plug and maintained once the mixture is burning rapidly. The massive expansion of the burning gas, is used to push the piston. In a CI (compression ignition diesel) engine, The air is drawn in, diesel fuel is sprayed into it and the piston compresses it. This compression alone, causes heat, which is enough to cause combustion. The same expansion of the burning gas, is used to do work on the piston.
Does Rarefaction refer to the compression of air molecules?
True.
What is the area of compression and rarefaction?
Compression is a Pushing Force whereas Rarefaction is a Pulling Force[Compression is the point when the most force is being applied to a molecule&Rarefaction is the point when the least force is applied].Compression happens when particles are forced/pressed together.Rarefaction is just the opposite,it occurs when particles are given extra space&allowed to expand.Compression&Rarefaction are Effects the wave causes.If you look at any normal visual representation of a Sound Wave,the humps above the middle line are called Compressions,the humps below are called Rarefactions.
How does the expansion of air affect temperature?
It cools.
What happens to air after repeated compression and expansion?
dats wat i m asking!! god 2morrow gotta summit d project............n i need d ans!!
What happens to air temperature when it is compressed or allowed to expand?
Heats with compression, cools with expansion.
Changes in temperature that result solely from the expansion or compression of air are called?
adiabatic
Air and fuel intake compression and ignition combustion and expansion and exhaust are sequential steps in?
The four-stroke engine cycle.
What is the correct sequence of strokes in a four-stroke engine?
Air and fuel intake, compression and ignition, combustion and expansion, exhaust
What happens in the upstroke of the piston in the crankcase in a four stoke engine?
On compression the air is compressed, and on exhaust it is forced out of the cylinder.On compression the air is compressed, and on exhaust it is forced out of the cylinder.
What happens when compressed air is suddenly let out like a puncture of a can?
You could get a couple of results. If the can is not secure it will probably become a projectile if the released air can overcome it's weight. The second thing that will happen is the compressed air will rapidly expand causing it to cool. That is how the compressor on an air conditioner works. Compression, then rapid expansion cools.
What is the correct sequence of steps in the four stroke engine cycle?
air and fuel intake, compression and ignition, combustion and expansion, exhaust
Does air push a bullet out of the barrel?
Air and gas. What happens is conflagration, which is halfway between an explosion and an expansion of gas and air.
Which of the following sequences describes how a four stroke engine cycle powers the engine?
Air and fuel intake, compression and ignition, combustion and expansion, exhaust
What is the difference between air conditioners and air coolers?
A; air conditioning works on the principle of gas compression and expansion which tends to remove water molecules from the air. Air cooler just provide air flow to distribute evenly the air and probably add water to the environment
What happens to the air particles above the drumhead when the drumhead moves downward?
it makes up a series of compression and rarefaction.
