NEET Chemistry First Law MCQ Question
Which of the following combinations correctly describes the First Law of Thermodynamics?
The change in internal energy is dependent on the path taken.
The energy of an isolated system is constant.
The internal energy change can be expressed as ∆U = q + w.
Heat transfer and work done are independent of internal energy change.
Correct Answer
Detailed Explanation
The First Law of Thermodynamics states that the energy of an isolated system is constant, meaning that the total energy remains unchanged regardless of how the change occurs. Additionally, the equation ∆U = q + w describes the relationship between internal energy, heat, and work, which is a key part of understanding the law.
