Is this thermo process reversible?

AI Thread Summary
The discussion centers on whether mixing 0.8kg of water at 100°C with 0.8kg of water at 0°C is a reversible process. The calculated entropy change for the process is 81.1 J/K, leading to the question of reversibility. It is noted that entropy generation typically indicates an irreversible process. The confusion arises from the relationship between entropy and reversibility, with a reminder that irreversible processes generate entropy. The conclusion emphasizes that the mixing of water at different temperatures is indeed irreversible due to the increase in entropy.

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?

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!

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
