Answer:

The Celsius scale starts at the freezing point of water (0°C) and than scaled so that 100°C fell on the boiling point of wate

Explanation:

Answer 2

There are two reference points marked on a thermometer. One reference point represents freezing point of water. Freezing point of the water is the temperature at which water starts converting into ice. As per Celsius scale, zero degree is the freezing point of the water.

A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a tree, or a sign - make good reference points.
