Question

Which of the following statements are TRUE with respect to heat and work? (i) They are boundary phenomena (ii) They are exact differentials (iii) They are path functions

Correct answer (B) both (i) and (iii) Solution Heat and work are both path functions because their values depend on the specific process path taken between states, not just the end states. Consequently, they are inexact differentials. Furthermore, they are boundary phenomena because they are only recognized as they cross the boundary of a system. Thus, statements (i) and (iii) are true. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
