can anybody tell me whats control volume?
Pressure and temperature Look into the gas Laws (Boyle, Lussac, Avogadro, etc.)
In fluid mechanics and thermodynamics, a control volume is a mathematical abstraction employed in the process of creating mathematical models of physical processes. In an inertial frame of reference, it is a volume fixed in space or moving with constant velocity through which the fluid (gas or liquid) flows.
Control volume is the amount of fluid entering into a system is maintained or delibrately constant at a particular volume.
