NEET Chemistry First Law MCQ Question
What does the equation ∆U = q + w represent in thermodynamics?
The change in internal energy of a system.
The total energy of a closed system.
The heat transferred at constant pressure.
The work done on a system at constant volume.
Correct Answer
Detailed Explanation
The equation ∆U = q + w expresses the first law of thermodynamics, indicating that the change in internal energy (∆U) is the sum of heat added to the system (q) and the work done on the system (w).
