The normal boiling temperature for water is 100° when measured on which scale?

Explanation:
Water’s boiling point at standard atmospheric pressure is defined on scales by fixed reference points. On the Celsius scale, 0 is the freezing point of water and 100 is its boiling point at 1 atmosphere, so the normal boiling temperature is 100°. On other scales the same event occurs at different numbers (232? No, 212 on Fahrenheit, about 373.15 on Kelvin, around 671.67 on Rankine). Since the question points to the scale where the boiling point is labeled 100, the appropriate scale is Celsius.
