The correct Answer is:
To solve the given question, we need to analyze both statements carefully. ### Step 1: Understand Statement 1 **Statement 1:** "In adsorption, the molecules of a substance are uniformly distributed throughout the body of another substance." - **Analysis:** This statement is incorrect. Adsorption refers to the process where molecules adhere to the surface of a solid or liquid, rather than being uniformly distributed throughout the bulk of the material. In adsorption, the concentration of the adsorbate is higher at the surface than in the bulk. ### Step 2: Understand Statement 2 **Statement 2:** "In some cases, both absorption and adsorption take place simultaneously." - **Analysis:** This statement is correct. There are scenarios where both processes occur together. For example, when a dye is applied to cotton, the dye molecules can both adsorb onto the surface of the cotton fibers and also be absorbed into the fibers themselves. ### Step 3: Conclusion - **Final Evaluation:** - Statement 1 is **incorrect** because it describes absorption rather than adsorption. - Statement 2 is **correct** as it accurately describes a situation where both processes can occur simultaneously. ### Answer: - **Both statements are correct, but Statement 2 is not the correct explanation of Statement 1.** Therefore, the correct answer is that Statement 1 is false and Statement 2 is true.
