Question

Which one of the following statements is false?

• A. Work is a state function
• B. Temperature is a state function
• C. Change in the state is completely defined when the initial and final states are specified
• D. Work appears at the boundary of the system

Answer 1

The correct option is A

Work is a state function

Explanation for correct option

(A) Work is a state function

State and path function

• State functions or point functions are properties whose value is independent of the path followed to obtain that value.
• Path functions are qualities or quantities whose values are determined by a system's transition from its initial to the final state.

Work is a path function

• Work is dependent on the path between two points.
• Work is a path function. Hence the given statement is false.

Explanation for incorrect options

(B) Temperature is a state function

• It is true that temperature is a state function.

(C) Change in the state is completely defined when the initial and final states are specified

• It is true that state change completely depends on the initial and final states.

(D) Work appears at the boundary of the system

• It is true that work appears at the boundary of the system.

Therefore, the correct option is (A) Work is a state function.
