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.

Q1.
In a piston-cylinder assembly attached with spring load is filled with 60 kg of water at pressure of
250 kPa and temperature of 25°C. The piston has base area of 0.1 m² (see Figure Q1). Heat is
added into the water and the volume expands to 0.2 m? and just touches the spring that has spring
constant k =100 kN/m.
Further heat is added and the piston starts to push the spring and the piston rises 20 cm compressing
the spring. By considering the necessary assumptions, determine
(a) the pressure and temperature at the end of the process,
(b) the work done in the process, and discuss about the significant of the sign of work done on
the process.
(c) show the process on P-V diagram, and discuss the initial state and final state of the water.
