The correct Answer is:
To solve the question regarding the existence of a substance in more than one solid modification, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: The question asks for the term that describes a substance existing in multiple solid forms or modifications. 2. **Analyze the Options**: - **Isomorphism**: This term refers to different substances that have the same crystalline structure or shape. It does not apply to a single substance existing in different forms. Therefore, this option is not correct. - **Polymorphism**: This term specifically refers to the ability of a substance to exist in more than one crystalline form. For example, sulfur can exist in different forms such as rhombic and orthorhombic. This option fits the question perfectly. - **Amorphism**: This term refers to the lack of a definite crystalline structure, which is characteristic of amorphous solids. It does not pertain to the existence of a substance in multiple solid forms. Thus, this option is also incorrect. - **None of these**: Since we have identified polymorphism as the correct term, this option is not applicable. 3. **Select the Correct Answer**: Based on the analysis, the correct answer is **polymorphism**. ### Final Answer: The existence of a substance in more than one solid modification is known as **polymorphism**. ---
