NEET Chemistry First Law MCQ Question
Which of the following statements about the First Law of Thermodynamics is correct?
The change in internal energy depends only on the initial and final states of the system.
Heat transfer and work done are state functions that define the internal energy change.
Energy can be created or destroyed in an isolated system.
The equation ∆U = q + w is applicable only for isothermal processes.
Correct Answer
Detailed Explanation
The change in internal energy (∆U) is indeed a state function that depends only on the initial and final states, as stated in the First Law of Thermodynamics: ∆U = q + w.
