A gas is compressed to half its volume in two different ways : (i) very rapidly. In which process will the work done on the gas behigher? |
|
Answer» Solution :LET the initial state of the gas be represented by the point A on a pV DIAGRAM. (i) When the gas is compressed very rapidly. It is an adiabaticprocess. This COMPRESSION from VOLUME V to volume `V/2` is represented by the curve AB. So the work done on the gas = area under there curve AB = area ABDEA. Then clearly, area ABDEA > area ACDEA. This MEANS that a higher amount of work will be done on the gas in the rapid process.
