Zero is the freezing temperature of water on which temperature scale?

• A. Celsius
• B. Fahrenheit
• C. Kelvin
• D. Rankine

Answer: (A)

Verified step by step guidance

1. Understand that temperature scales are different ways to measure temperature, each with its own reference points.
2. Recall that the Celsius scale sets 0 degrees as the freezing point of water and 100 degrees as the boiling point of water at standard atmospheric pressure.
3. Recognize that the Fahrenheit scale sets the freezing point of water at 32 degrees and the boiling point at 212 degrees.
4. Know that the Kelvin scale is an absolute temperature scale starting at absolute zero, with 273.15 K as the freezing point of water.
5. Identify that the Rankine scale is similar to Kelvin but uses Fahrenheit degree increments, so its freezing point of water is 491.67 degrees Rankine.
