Practice question · True or false
Heat and work are both state functions of a system.
Hints
- Can you ask how much heat a system currently contains?
- Both are energy in transit and depend entirely on the route taken.
Show the answer
False
Why
False, neither is a state function. A system holds internal energy, not heat or work; both are modes of transfer whose values depend on the path, which is why the same can be reached with completely different splits of and .
