Is this thermo process reversible?

Click For Summary
SUMMARY

The discussion centers on the reversibility of a thermal process involving 0.8 kg of water at 100 degrees Celsius mixed with 0.8 kg of water at 0 degrees Celsius. The calculated entropy change for this process is 81.1 J/K. It is established that the generation of entropy indicates an irreversible process, confirming that this thermal mixing is not reversible. The confusion arises from the relationship between entropy generation and process reversibility, which is clarified in the discussion.

Homework Statement


If 0.8kg of water at 100 celsius is mixed with 0.8kg of water at 0 celsius, is this process reversible?


Homework Equations


Entropy:
S = mcln(T_2/T_1)



The Attempt at a Solution


I've already calculated the entropy of the process, which is 81.1 J/K. But how do I know if it's reversible?
 
Physics news on Phys.org
How can it be reversible if entropy is generated? Entropy is generated for irreversible processes right? I think I remember this, but correct me if I'm wrong.
 
Oh. I seemed to have skipped that part of the lecture. Thank you!
