which of the following quantities is not a State function? options a) temperature b) entropy c) enthalpy d) work
Answers
(d) Work is not a State Function.
Reason -
Work done by the system or surroundings depend on the process or path by which the final state is achieved. Work done in a system depends on what path is chosen to go from state 1 to state 2. So, work is a path function as different paths give different quantities.
Option D-work is the answer.
Explanation:
Work is not a state function as its value depends on the path followed by the the process in going from one point to another.
Its value changes with the path followed .
For example- if it takes 150J of energy to go from point A to B but it will take 180J if one goes from A to B through a point C not lying in the path.
hence Work is not a state function.
