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


Re: pressure

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

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.
