Neither `q` nor `w` is a state function but `q +w` is a state function. Explain why?

q and w are not state function but q + w is state function. Why?

A: q and w are path function R: q + w is a state function

Heat and work are not state function but their sum is a state function.

Which of the following statement is correct? (A) only internal energy is a state function but not work (B) only work is a state function but not internal energy (C) Both internal energy and work are state functions (D) Neither internal energy nor work is state function

Assertion(A) : q is a state function. Reason(R ) : q is a path function.

Assertion: Work and internal energy are not state functions. Reason: The sum of q+w is a state function.

Both q & w are __________ function & q + w is a ___________ function :-
