Question

Two identical copper ingots,
one at 500°C and the other at
300°C are
placed in an insulated enclosure. Heat
flows from the hot ingot to
the cold ingot until the temperature of
both ingots is the same (400°C.
Calculate the total enropy change
accompanying this process, assuming
that the transfer of heat from the ingots
to the material of construction
of the enclosure is negligible. Given:
C(Cu) = 5.41 +1.5 x 10-3Tcal/K/mol​
