The correct Answer is:
To solve the question regarding the statement made by the student about the energy of a particle at 0 K, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Statement**: The student claims that the energy of a particle does not become zero at 0 K (absolute zero). We need to evaluate the validity of this statement. 2. **Concept of Absolute Zero**: At absolute zero (0 K), classical thermodynamics suggests that a system would be in its lowest energy state. However, quantum mechanics introduces the concept of zero-point energy. 3. **Zero-Point Energy**: According to quantum mechanics, even at 0 K, particles retain a certain amount of energy known as zero-point energy. This is due to the Heisenberg Uncertainty Principle, which states that we cannot precisely know both the position and momentum of a particle simultaneously. 4. **Evaluate the Options**: - **Option A**: The student made a wrong statement. This is incorrect because the student's statement aligns with quantum mechanics. - **Option B**: The student made a correct statement according to the kinetic theory of gases. This is incorrect because the kinetic theory does not account for quantum effects. - **Option C**: The student made a correct statement according to the quantum theory of electromagnetic radiation. This is incorrect as it does not specifically address the energy of particles at 0 K. - **Option D**: The student made a correct statement according to the Heisenberg uncertainty principle. This is correct because it explains why energy cannot be zero at absolute zero. 5. **Conclusion**: The correct opinion is that the student made a correct statement, and it is supported by the Heisenberg uncertainty principle. Therefore, the correct option is D. ### Final Answer: The correct option is D: The student made a correct statement and it is according to the Heisenberg uncertainty principle. ---
