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.

Question

Problem 1.
A piston-cylinder device initially contains steam at 200 kPa, 250 °C, and 0.4 m². In
this state, a linear spring (Fax) touches the plunger, but exerts
no force on it. Then, heat is slowly transferred to the steam,
causing its pressure and volume to increase, up to 250 kPa and 0.55
m², respectively. Represent the process on the P-v and T-v
diagrams with respect to saturation lines, and determine: 1)
the properties of state 1 (T; P; Vi; u; h; s. 2) the properties
of state 2 (T2: P2, V2, uz, h, s. 3) The change of: specific
volume, internal energy, enthalpy, entropy. 4) the work done by the
steam. 5) the total heat transferred.
