Verified Answer
Direction: In the following questions, a statement of Assertion (A) is...
Explanation: Both the statements are correct. Sublimation is a process where a substance changes directly from solid to vapour without passing through liquid state. On the other hand, distillation is a process that involves vaporization and condensation. However, the reason does not explain the assertion as both are different processes. Sublimation is a single step process, while distillation is a two-step process.

Direction: In the following questions, a statement of Assertion (A) is...
Assertion : In sublimation, a substance changes directly from solid to vapour without passing through the liquid state and vice-versa.
Reason : Distillation involves two processes i.e., vaporisation and condensation.
Explanation:
Sublimation and Distillation are two different processes that involve the conversion of a substance from one state to another. Let's understand each process separately and then analyze the given Assertion and Reason.
Sublimation:
- Sublimation is the process in which a substance directly changes from the solid state to the gaseous state without going through the liquid state.
- This occurs when the substance's vapor pressure exceeds its triple point pressure at a given temperature.
- Examples of substances that undergo sublimation include iodine, dry ice (solid carbon dioxide), and naphthalene (mothballs).
Distillation:
- Distillation is a process used to separate components of a mixture based on their different boiling points.
- It involves two main steps: vaporization and condensation.
- During vaporization, the liquid mixture is heated, and the component with the lowest boiling point evaporates and becomes vapor.
- The vapor is then cooled and condensed back into a liquid, which is collected separately.
- This process allows the separation of different components based on their boiling points.
Analysis:
- The Assertion states that in sublimation, a substance changes directly from solid to vapor without passing through the liquid state and vice-versa. This statement is true.
- The Reason states that distillation involves two processes, vaporization, and condensation. This statement is also true.
- However, the Reason does not provide a correct explanation for the Assertion because distillation involves the conversion of a liquid into vapor and then back into a liquid, while sublimation involves the direct conversion of a solid into vapor.
- Therefore, both the Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion.
Conclusion:
The correct answer is option 'B' - Both (A) and (R) are true, but (R) is not the correct explanation of (A).
