The correct Answer is:
To determine whether surface area is a scalar or a vector quantity, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Surface Area**: - Surface area refers to the total area that the surface of an object occupies. It is a measure of how much exposed area an object has. 2. **Defining Scalar and Vector Quantities**: - A **scalar quantity** is defined as a quantity that has only magnitude (size) and no direction. Examples include mass, temperature, and area. - A **vector quantity**, on the other hand, has both magnitude and direction. Examples include velocity, force, and displacement. 3. **Analyzing Surface Area**: - The unit of surface area is square meters (m²), which indicates that it is a measure of extent in two dimensions. - Surface area does not have a direction associated with it; it simply quantifies the extent of a surface. 4. **Conclusion**: - Since surface area has only magnitude and no direction, it is classified as a scalar quantity. 5. **Choosing the Correct Option**: - Based on the definitions and analysis, the correct answer to the question is that surface area is a scalar quantity. ### Final Answer: - The correct option is: **Option 1: Scalar**.
