Internal Energy As A State Function And Heat

"Internal energy is a state function." Explain.

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

Explain internal energy as a state function.

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

Assertion (A): Internal energy change in a cyclic process is zero Reason (R ): Internal energy is a state function
