NEET Physics Heat Engines MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Which of the following statements about thermodynamics is correct?

A

The change in internal energy, ∆U, is a state function.

B

Heat (q) and work (w) are state functions.

C

The decomposition of CaCO3(s) is an exothermic process.

D

Gibbs energy change is independent of temperature.

Correct Answer

Option A

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.
