How does pressure will increase when we compress the air?

[rameshbabu]

when we compress the air , how the pressure will increase.
when pressure increases does the energy increases.

pressure

P=V*n*R*T

That should explain everything.

dude i think it is PV=nRT....

You're right, it is PV=nRT. Take a look at this wikipedia article: https://en.wikipedia.org/wiki/Standard_conditions_for_temperature_and_pressure

I wonder why people don't event try searching the net before asking...

Re: pressure

rameshbabu,
In answer to the second part of your question, If the pressure increases due to external influences, the energy does increase.

O yea, oops! me bad! Sorry.

Re: pressure

If we try to compress air container, some work is done on the air or its container ..

So , this work done in compressing is used to raise the internal internalenergy of air molecules.
Hence , energy increases.


PV = constant , where P is pressure, V is Volume.

P is inversely proportinal to volume .i.e. due to compression as the volume decreases the pressure increses.

pressure

V is volume and it is a container. v is const.

So if ull increase pressure there will be more molecules in a container, due it energy will increase coz molecules are energy and als o they want room to play, so ull get higher pressure.

Pressure is force per area. not volume...

But thease 2 are very much related to eo.
