(15 POINTS) Exergy analysis of the melting of a piece of ice
In this exercise you are asked to evaluate the exergy changes (lost work) associated with
the melting of an ice lump of mass of 1kg and an initial temperature of 245K as it
becomes in contact with the environment assumed at a temperature of 293K. The
whole process can be assumed to be at 1 bar of pressure.
You can use the following information:
Enthalpy of fusion of water: hw=333.4kJkg
Isobaric specific heat capacity of ice: cP,i=2.07kJkgK
Isobaric specific heat capacity of water: cP,w=4.20kJkgK
Melting temperature for ice under 1 bar of pressure: Tm=273.16K
