Celsius scale

The Celsius scale sets the freezing point and boiling point of water at 0°C and 100°C respectively. The Kelvin scale is based on molecular motion, with the temperature of 0 K, also known as absolute zero, being the point where all molecular motion ceases.

Answer 2

$\sf\huge\bold{Answer:}$

The scale in which the melting point of ice and the boiling point of water are taken as 0 and 100, respectively .

• $\tt\red{Celsius \:Scale.}$

Principal of Celsius scale :

• The Celsius scale is based on a derived unit defined by assigning the temperatures of 0°C and 100°C to the freezing and boiling points of water, respectively, at 1 atm pressure.

• The Celsius scale is defined by absolute zero and the triple point of pure water.

Inventors of Celsius scale :

This scale was first introduced and invented by (and is named after) the Swedish physicist, astronomer, and engineer Anders Celsius.
