NEET Physics Heat Engines MCQ Question
Which of the following statements about thermodynamics is correct?
The change in internal energy, ∆U, is a state function.
Heat (q) and work (w) are state functions.
The decomposition of CaCO3(s) is an exothermic process.
Gibbs energy change is independent of temperature.
Correct Answer
Detailed Explanation
According to the text, ∆U, the change in internal energy, is a state function while heat (q) and work (w) are not. Additionally, the decomposition of CaCO3(s) is described as endothermic, and Gibbs energy change is dependent on temperature.
