Practice question · True or false
The thermodynamic identity holds even for irreversible processes.
Hints
- Are all the terms in it state functions?
- Every term is a state-function differential, so the relation is path-independent.
Show the answer
True
Why
True, every quantity in it is a state function, so the relation between them holds regardless of the path taken. This is exactly why it is more powerful than the first law written in terms of heat and work.
