Water, assumed to be a perfect liquid, has a density of 1000 kg/m³ and a specific heat of 4184 J/kgK. The water undergoes an adiabatic, frictionless process in which its pressure is raised from 100 kPa to 1000 kPa. Find the following: (a) the change of specific internal energy (J/kg) (b) the change in temperature (K) (c) the change of specific enthalpy (J/kg) (d) the temperature change (K) required in a non-adiabatic but isobaric process to change the enthalpy the same amount as the change in part c.

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.
