Consider the following statements
I. Boiling point of water is 273 K.
II. Evaporation takes place at all temperature.
Which of the statement(s) given above is/are correct?

Options

A. Only I
B. Only II
C. Both I and II
D. Neither I nor II

Explanation

To solve the question, we need to evaluate the two statements provided:

1. **Statement I**: Boiling point of water is 273 K.
2. **Statement II**: Evaporation takes place at all temperatures.

### Step 1: Analyze Statement I
- The boiling point of water is commonly known to be 100°C at standard atmospheric pressure. To convert this to Kelvin:
\[ 100°C + 273.15 = 373.15 K \]
- Therefore, the boiling point of water is approximately 373 K, not 273 K. This means **Statement I is incorrect**.

### Step 2: Analyze Statement II
- Evaporation is the process where liquid turns into vapor. This process can occur at any temperature, even at temperatures below the boiling point.
- For example, water can evaporate at room temperature. Thus, **Statement II is correct**.

### Step 3: Conclusion
- Since Statement I is incorrect and Statement II is correct, the answer to the question is that only the second statement is correct.

### Final Answer
- The correct option is: **Only statement II is correct**.
