Which of the following statements correct?
Correct answer: C. Both heat and work are interconvertible.
- A. Work can never be converted into heat.
- B. Work can be converted completely into heat.
- C. Both heat and work are interconvertible.
- D. Heat can never be converted into work.
- E. Heat can be converted completely into work.
Explanation
Yes, heat and work are interconvertible forms of energy. In thermodynamics, they can be transformed into each other.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
