The correct Answer is:
To solve the question, we need to analyze both statements provided: **STATEMENT - 1:** An increase in surface area increases the rate of evaporation. **STATEMENT - 2:** Stronger the intermolecular attraction force, faster is the rate of evaporation at a given temperature. ### Step 1: Analyze Statement 1 - **Understanding Evaporation:** Evaporation is the process where liquid turns into vapor, occurring at the surface of the liquid. - **Effect of Surface Area:** When the surface area of a liquid increases, more molecules are exposed to the air. This means that more molecules can escape into the vapor phase. - **Conclusion for Statement 1:** Therefore, an increase in surface area does indeed increase the rate of evaporation. This statement is **true**. ### Step 2: Analyze Statement 2 - **Understanding Intermolecular Forces:** Intermolecular forces are the forces of attraction between molecules. Stronger intermolecular forces mean that molecules are held together more tightly. - **Effect of Strong Intermolecular Forces on Evaporation:** If the intermolecular forces are strong, it becomes harder for molecules to escape into the vapor phase. Thus, the rate of evaporation decreases when intermolecular forces are strong. - **Conclusion for Statement 2:** Therefore, the statement that stronger intermolecular attraction forces lead to a faster rate of evaporation is **false**. ### Final Conclusion - **Statement 1 is true.** - **Statement 2 is false.** Thus, the correct answer is that Statement 1 is true, and Statement 2 is false. ---
