Scientist Use The Celsius Scale. Using a mercury thermometer the Celsius scale consists of 100 degrees between the freezing point 0 C and boiling point 100 C of pure water at sea level air pressure. In addition Celsius and Kelvin another commonly used scale especially by scientists have the same unit size with the difference between scales.
So scientist prefer using the Kelvin scale when dealing with basic properties of matter because it simplifies the equations used. The Swedish astronomer Andres Celsius established the temperature scale in 1742. 2The freezing point of water being 0C and the boiling point being 100C is rather convenient for scientists what with water being an extremely common.
27 November 1701 25 April 1744 was a Swedish astronomer physicist and mathematicianHe was professor of astronomy at Uppsala University from 1730 to 1744 but traveled from 1732 to 1735 visiting notable observatories in Germany Italy and France.
The Kelvin scaleThe Kelvin scale is a temperature scale that is used a lot in astronomy. The only surviving portrait of Anders Celsius undated Uppsala University The surprise is that on his original scale 100 degrees was assigned to the freezing point of water and 0 degrees to the boiling point just the reverse of modern practice. The Celsius scale also known as the centigrade scale is a temperature scale based on 0 o for the freezing point of water and 100 o for the boiling point of water. Initially the celsius scale was used at 0 to denote the boiling point of water and 1000 to denote the freezing point of water.
