Two one-kilogram bars of gold are initially at 50°c and 300°c. the bars are brought in contact with each other. what is their final temperature, the entropy change of each block, and the total entropy generation in the process.
Answers: 1
= 50°C = 273+50 =323 K
= 300°C = 273+300 =573 K
= 
= 448K
=0.042 J/K
= 0.129ln 
= - 0.032 J/K 
= 
= 0.042 + (- 0.032) = 0.010 J/K
