Question
1) What is the change in entropy of the hot reservoir?
?SH = __________________ J/K
2) What is the change in entropy of the cold reservoir?
?Sc = ___________________ J/K
3) What is the change in entropy of the whole universe due to this process?
?S = ___________________ J/K
A piece of equipment functions such that a hot reservoir at 603 K transfers 1100 J of heat irreversibly to a cold reservoir at a temperature of 293 K. What is the change in entropy of the hot reservoir? What is the change in entropy of the cold reservoir? What is the change in entropy of the whole universe due to this process?Explanation / Answer
Sh = Q/T
= -1100/603
= -1.824 J/K
Sc = 1100/293
= 3.754 J/K
Suniverse = Sh + Sc
= 1.930 J/K
