NEET Physics Laws of Thermodynamics MCQ Question
Which of the following combinations about the laws of thermodynamics is correct?
The first law states that energy cannot be created or destroyed, and the second law states that entropy of an isolated system never decreases.
The first law allows for the creation of energy under certain conditions, while the second law states that all processes increase system energy.
The first law applies only to chemical reactions, and the second law applies only to physical changes.
The first law deals with temperature changes, while the second law focuses on pressure changes in systems.
Correct Answer
Detailed Explanation
The first law of thermodynamics confirms that energy cannot be created or destroyed, and the second law states that in an isolated system, entropy tends to increase, indicating that the entropy of the system never decreases.
