Water, assumed to be a perfect liquid, has a density of 1000 kg/m and a specific heat of 4184 J/kgK. The water undergoes an adiabatic, frictionless process in which its pressure is raised from 103 kPa to 815 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.
