D200 RJIkg)
A cold block of ice is placed in a hot bowl made
of lead.
a) Find Tr in terms of the symbols shown in the
diagram.
b) Find the change in entropy of the bowl for this
process. (Leave your answer in terms of Tt.)
c) Next, find the change in entropy of the H20
for this process. (Again, leave your answer in
terms of Tr.)

d) For the combined bowl+H2O system, will the
total change in entropy ASsys be positive,
negative, or zero? Why?

e) Find ASsys (in terms of Tr). **
T.
After a while, we have bowl full of water, with
both the bowl and the water at the same
temperature Tr.
