Find the entropy change of the block

Reference no: EM13265871

A large block of copper initially at 20.0oC is placed in vat of hot water (80.0oC). For the first 1.0 J of heat that flows from the water into the block, find

(a) the entropy change of the block,

(b) the entropy change of the water,

(c) the entropy change of the universe. Note that the temperatures of the block and the water are essentially unchanged by the flow of only 1.0 J of heat.
