A gas cylinder with interior volume 11.1 L holds compress air at 17.2 MPa. The cylinder is joined by a hose of negligi volume to a second cylinder that's been pumped down to vacuum. When the valve on the full cylinder is opened, the air expands to fill the entire system, all the while maintaining a constant temperature. If the energy that becomes unavailable to do work is 168.1 k), what's the volume of the second cylinder (L)?

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.
