Reversibility and Carnot cycle

Click For Summary
SUMMARY

The Carnot cycle is indeed completely reversible, as confirmed by the discussion participants. The principle of reversibility is rooted in the Clausius theorem, which states that for a reversible process, the change in entropy (\Delta S) is zero. This means that any increase or decrease in the system's entropy is perfectly balanced by an equal change in the surroundings, ensuring that the total entropy of the universe remains constant.

I have two short questions:

1) Is the Carnot cycle completely reversible?

2) [tex]\Delta S = 0[/tex] for a reversible process, right?
 
Science news on Phys.org
Yes, the Carnot cycle is designed as being reversible.

Yes, it is the Clausius theorem for a reversible cycle. On a particular reversible process, a system can increase o decrease its entropy provided that the surroundings decrease or increase it by the same amount, as the universe entropy will remain constant.
