Insulated container X and uninsulated container Y are connected with a valve both initially containing water steam. The initial state at X is 400kPa and x=80% where the volume is 0.2 m'. Container Y initially contains 3kg steam at 200kPa and 250°C. The valve is opened until the pressure in both containers is equal and 300kPa, and during this process 900 kJ heat is transferred from container Y to the surroundings. If the final temperature of X is 100°C what is the final temperature at container Y?

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.
