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

P=V*n*R*T
That should explain everything.

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

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

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.

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.
