Two copper blocks, each of mass 1.74 kg, initially have different temperatures,t1 = 18° C and t2 = 30° C. The blocks are placed in contact with each other and come to thermal equilibrium. No heat is lost to the surroundings.
(a) Find the final temperature of the blocks.
°C

Find the heat transferred between them.
J

(b) Find the entropy change of each block during the time interval in which the first joule of heat flows.

?S1 = J/K
?S2 = J/K


(c) Estimate the entropy change of each block after it has reached thermal equilibrium. Use each block's average temperature during the process in calculating the estimated values of ?S.

?S1 = J/K
?S2 = J/K
