- Enthalpy
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept: First law of thermodynamics states: \[ \Delta U = q + w \] It expresses that:
• Energy can neither be created nor destroyed.
• It can only be converted from one form to another.
Step 1: Interpret meaning.
This directly represents conservation of energy.
Step 2: Conclusion.
Thus, first law explains conservation of energy. Final Answer: Option (C)
