A and B are two liquids at room temperature taken in containers of the same dimension and only liquid A can get converted into gaseous state below its boiling point. Identify the false statement regarding A andB.
(A) A is highly volatile and the process associated with B is quick.
(B) The process associated with A is a surface phenomenon and liquid B is less volatile.
(C) The process associated with B causes cooling and the process associated with A is boiling.
(D) The process associated with A is slow and the process associated with B is a surface phenomenon.

Options

A. (B) and (C)
B. (C) and (D)
C. (A) and (C)
D. (B) and (D)

Explanation

To solve the problem, we need to analyze the statements regarding the two liquids A and B based on the information provided.

### Step-by-Step Solution:

1. **Understanding the Properties of Liquid A:**
- Liquid A can convert into a gaseous state below its boiling point, indicating that it is highly volatile.
- The process associated with A is evaporation, which is a surface phenomenon and causes cooling.

2. **Understanding the Properties of Liquid B:**
- Since only liquid A can evaporate below its boiling point, liquid B must be less volatile and is likely to undergo boiling when heated.
- The process associated with B is boiling, which is a bulk phenomenon and is generally a quick process.

3. **Analyzing Each Statement:**
- **(A)** "A is highly volatile and the process associated with B is quick."
- This statement is true because A is indeed highly volatile, and boiling (the process associated with B) is quick.

- **(B)** "The process associated with A is a surface phenomenon and liquid B is less volatile."
- This statement is also true. The evaporation of A is a surface phenomenon, and B is less volatile compared to A.

- **(C)** "The process associated with B causes cooling and the process associated with A is boiling."
- This statement is false. The process associated with B (boiling) does not cause cooling; rather, it is the evaporation of A that causes cooling. Additionally, the process associated with A is evaporation, not boiling.

- **(D)** "The process associated with A is slow and the process associated with B is a surface phenomenon."
- This statement is false. While the process associated with A (evaporation) is indeed slow, the process associated with B is boiling, which is a bulk phenomenon, not a surface phenomenon.

4. **Identifying the False Statements:**
- From the analysis, statements C and D are false.

### Conclusion:
The false statements regarding liquids A and B are (C) and (D).
