Which temperature scale uses 32 degrees as the freezing point of water?

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

Answer: (D)

Verified step by step guidance

1. Understand that temperature scales are different ways to measure temperature, each with its own reference points for freezing and boiling of water.
2. Recall the freezing point of water in Celsius is 0 degrees, and in Kelvin it is 273.15 K, so these scales do not use 32 degrees for freezing.
3. Know that the Rankine scale is an absolute temperature scale like Kelvin but uses Fahrenheit degree increments, so its freezing point is not 32 degrees.
4. Recognize that the Fahrenheit scale sets the freezing point of water at 32 degrees Fahrenheit, which is a unique characteristic of this scale.
5. Therefore, the temperature scale that uses 32 degrees as the freezing point of water is the Fahrenheit scale.
