- D$q/w$
✓
Answer
Correct option: C.
$q + w$
c
Both work and heat are path functions. Their values depends on the path chosen to reach a particular state.
Both work and heat are path functions. Their values depends on the path chosen to reach a particular state.
However, the change in internal energy which is equal to the sum of heat and work, is a state function. Its value is independent of the path chosen to reach a particular state.
