The correct Answer is:
To solve the assertion and reason question, we will analyze both statements step by step. ### Step 1: Analyze the Assertion **Assertion:** Glassy solids have a sharp melting point. - Glassy solids, also known as amorphous solids, do not have a definite or sharp melting point. Instead, they soften over a range of temperatures. This is because the structure of glassy solids lacks a long-range order, which is characteristic of crystalline solids. **Conclusion for Assertion:** The assertion is **false**. ### Step 2: Analyze the Reason **Reason:** The bonds between the atoms of glassy solids get broken at the same temperature. - In glassy solids, the bonds between the atoms or molecules are not uniform in strength. Different bonds can break at different temperatures due to variations in their strengths. This means that there is no single temperature at which all bonds break simultaneously. **Conclusion for Reason:** The reason is also **false**. ### Step 3: Final Conclusion Since both the assertion and the reason are false, we conclude that the correct answer is that both the assertion and the reason are false. ### Final Answer: Both assertion and reason are false. ---
