Homework Statement


Hi !

I'm stuck with these two questions of my assignment of thermodynamics

- Give two exemples of irreversible process (initial state, process, final state)
- For each of them, explain why they are irreversible on the microscopic scale.

Homework Equations


We are not asked any calculations here. I only need to describe with a few sentences.

The Attempt at a Solution


irreversible process => exemple : An engine (?) There's an irreversible process because of the Joule heating and frictions.
