What is the freezing point of water on the Celsius temperature scale?

• A. 100
• B. -273
• C. 32
• D. 0

Answer: (D)

Verified step by step guidance

1. Understand that the freezing point of water is the temperature at which liquid water turns into solid ice under standard atmospheric pressure.
2. Recall the Celsius temperature scale, where 0 degrees Celsius is defined as the freezing point of pure water.
3. Recognize that the other options (100, -273, 32) correspond to different temperature points: 100°C is the boiling point of water, -273°C is absolute zero, and 32°F is the freezing point of water on the Fahrenheit scale.
4. Therefore, identify that the freezing point of water on the Celsius scale is 0°C.
5. Conclude that the correct answer to the question is 0.
