He chose water because it is world's most common liquid to test.
Anders Celsius
Celsius was invented as a way of measuring temperature. A scientist named Anders Celsius put a thermometer in water until it froze, and marked where the mercury level was. He then measured the level in boiling water. The temperature in boiling water was given 100 Celsius, freezing was given 0 Celsius.
Anders Celsius was the man who created a mercury thermometer which showed water freezing at 0 degrees and boiling at 100 degrees. He was a Swedish astronomer, physicist and mathematician.
Swedish scientist Anders Celsius neither invented nor improved the thermometer. What he did, in 1742, was to propose a thermomenter scale with 100 divisions between water's boiling point and its freezing point. The scale developed by Celsius was actually the reverse of the scale we use today. He placed 0 at water's boiling point and 100 at its freezing point. So the Celsius temperature scale was not actually his "invention"; it is simply named in his honor.
If you mean "what temperature scale" it is Celsius (C). The scale is based upon the freezing and boiling points of pure water at sea level. Water freezes at 0 C and boils at 100 C. It is named after Swedish astronomer Anders Celsius.
He created the Celsius scale by determining when water boils and freezes. (100 and 0 degrees Celsius, respectively).
Of water, zero degrees
The boiling point of water is 100 degrees Celsius and the melting point of water is 0 degrees Celsius
Then the thermometer will show over 110 degrees Celsius - if it doesn't break first.
Anders Celsius invented the degree Celsius. He defined the freezing point of pure water as zero degrees, the boiling point of pure water as 100 degrees, and defined a linear progression between those two states. Hope this helps!
0º is the freezing point of water in Celsius.Zero. (that's how you calibrate your thermometer)
That depends on what units the thermometer is calibrated in. The SI unit for temperature is the kelvin, but degrees Celsius commonly used, if the thermometer reads in kelvin or degrees Celsius then it is a metric tool.
