Consider an ice cube with a mass of 1 g at 0∘C
that is left sitting on a kitchen table, where it undergoes gradual
melting (the temperature in the kitchen
is 25∘ C).
(a) Calculate ΔSsys for the melting of the ice
cube and the liquid water reaching thermal equilibrium with
the kitchen. (b) Calculate the ΔS of the
kitchen as it gives up heat to the melting ice cube/liquid water
basically calculate ΔSsurr.
(c) Calculate the net change in the entropy of the universe
associated with this process.
(d) Is the result in part (c) reasonable? Explain
Have each answer in J * K ^-1
