Which of the following is the freezing point of water on the Celsius scale?

• A. 32
• B. -273
• C. 0
• D. 100

Answer: (C)

Verified step by step guidance

1. Understand that the freezing point of water is the temperature at which water changes from liquid to solid under standard atmospheric pressure.
2. Recall the Celsius temperature scale, where 0 degrees Celsius is defined as the freezing point of water and 100 degrees Celsius is the boiling point of water.
3. Recognize that 32 is the freezing point of water on the Fahrenheit scale, not Celsius.
4. Note that -273 degrees Celsius corresponds to absolute zero, the lowest possible temperature, not related to water's freezing point.
5. Conclude that the freezing point of water on the Celsius scale is 0 degrees Celsius.
