A insulating cylinder has an equal amount of gas on both sides of a movable piston, as shown in the above figure. Initially, the two compartments have equal volumes and their temperatures are 550 K and 250 K. The piston then moves slowly until it comes to rest at an equilibrium position. Find the final temperatures in the two portions.

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.
