The correct Answer is:
To determine the freezing point of water (H₂O), we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Concept of Freezing Point**: - The freezing point is the temperature at which a substance changes from a liquid to a solid. For water, this is the temperature at which it begins to freeze. 2. **Identify the Freezing Point of Water**: - The freezing point of water is commonly known to be 0 degrees Celsius (°C). 3. **Convert Celsius to Kelvin**: - To convert Celsius to Kelvin, we use the formula: \[ K = °C + 273.15 \] - Substituting the freezing point of water: \[ K = 0 + 273.15 = 273.15 \, K \] 4. **Conclusion**: - Therefore, the freezing point of water (H₂O) is 273.15 Kelvin (K). ### Final Answer: The freezing point of H₂O is **273.15 K**. ---
