8) Consider two initially separate blocks of copper in an
isolated container. Each
block is of mass 15.0 kg, and one is at 100C and the other at 25C.
They are placed in contact and allowed to equilibrate. Refer to the
prescribed textbook
Resource section for data. The molar heat capacity is to be
regarded as constant
over the temperature range. Calculate the total change in entropy
and rationalize
the result. [7]
