Two copper blocks, each of mass 2.12 kg, initially have different temperatures,t1 = 18° C and t2 = 26° 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

Find the heat transferred between them.

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

Delta S1=
Delta S2=

(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 ΔS.
