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

Which of the following expressions is true if the expression PltTlt=qgtSgtMgt=W is definitely true ?

Assertion: Between two thermodynamic states, the value of (Q-W) is constant for any process. Reason: Q and W are path functions.

Assertion: Between two thermodynamic states, the value of (Q-W) is constant for any process. Reason: Q and W are path functions.

p ^^ q is true when : ( a) p and q are both true (b) p and q are both false ( c ) p is true and q is false ( d) p is false and q is true.

Which is not a state function: (q+w),w,H,G ?

If p and q are two statement then (p ~ q) is true when : (a) p and q both are true (b) p and q both are false (c) p is false and q ia true (d) Non of these
