Which statement(s) about state functions is(are) correct?
(i) State functions are the opposite of path-dependent functions.
(ii) State functions have no “memory” about how they arrived at a given value.
(iii) State functions are path-dependent functions.
(iv) Heat and work are not state functions and neither is their sum a state function.
State functions:
The properties of a substance which depend on the extent of the sample mean amount of the substance in the sample are known as extensive properties. Such as, mass, volume etc. An extensive property depends only on initial and final state of system and surrounding not on path.
Path functions:
In thermodynamics; some functions are depends only path not initial and final state of system and surrounding, these are known as path function.
The following statement(s) about state functions is(are) correct:
(i) State functions are the opposite of path-dependent functions.
(ii) State functions have no “memory” about how they arrived at a given value.
