The first law of thermodynamics is a special case of :
Correct answer: C. Conservation of energy
- A. Newton's law
- B. Charles's law
- C. Conservation of energy
- D. Conservation of entropy
Explanation
First law of thermodynamics states that change in internal energy of the system is equal to heat transferred to the system and work done by the system. Mathematically,ΔU = Q - WThe first law of thermodynamics advocates that energy can neither be created nor be destroyed in an isolated system. It correlates to the law of conservation of energy, that states that energy of an isolated system must remain constant. Hence, C option is the correct.

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.
