NEET Chemistry (general) MCQ Question
Which of the following statements regarding isothermal processes and internal energy are correct?
In isothermal expansion of an ideal gas, ∆U = 0.
For isothermal processes, heat supplied is equal to work done.
In isothermal irreversible changes, q is not equal to -w.
Internal energy is always a function of temperature for ideal gases.
Correct Answer
Detailed Explanation
In isothermal processes involving ideal gases, the internal energy change (∆U) is zero because temperature remains constant, thus supporting statement A. Statement B is true in the context of isothermal processes but not directly from the provided content. Statement C is incorrect as it contradicts the definition. Statement D is a general principle not specifically derived from the context given.
