The correct Answer is:
To analyze the given statements and determine their validity, let's break down the problem step by step. ### Step 1: Understand Statement I **Statement I:** Small liquid drops assume spherical shape. **Explanation:** - When a liquid drop is formed, the molecules at the surface experience an inward force due to the attraction from the molecules inside the liquid. This results in the drop minimizing its surface area. - Among all possible shapes, a sphere has the smallest surface area for a given volume. Therefore, small liquid drops naturally take on a spherical shape. ### Step 2: Understand Statement II **Statement II:** Due to surface tension, liquid drops tend to have minimum surface area. **Explanation:** - Surface tension is the property of the liquid's surface that causes it to behave like a stretched elastic membrane. It arises from the cohesive forces between liquid molecules. - Because of surface tension, the liquid molecules at the surface are pulled inward, which leads to the formation of a shape that minimizes the surface area. This is why liquid drops tend to be spherical. ### Step 3: Analyze the Relationship Between the Statements - Statement I is true because small liquid drops do assume a spherical shape. - Statement II is also true because surface tension causes the liquid to minimize its surface area. - Furthermore, Statement II provides the correct explanation for Statement I since the spherical shape of the drop is a consequence of surface tension acting to minimize surface area. ### Conclusion Both statements are true, and Statement II correctly explains why Statement I is true. ### Final Answer: The correct option is: - Statement 1 is true, Statement 2 is true, and Statement 2 is the correct explanation of Statement 1. ---
