9.8 Centigrade Scale and Absolute Scale
In order that the thermodynamic scale chosen above may agree with the two fixed points of the centigrade scale, we take 373 engines in the chain, the top temperature of the chain being taken to be the boiling point of water under 760 mm Hg pressure. Then it takes 100 steps to come down to the melting point of ice and 273 more steps to convert the remaining heat of work to reach the zero of the absolute scale.
9.8.1 The Centigrade Scale of Temperature
In the centigrade scale of temperature, the melting point of ice under normal pressure of 760 mm of mercury is taken to the zero of the scale and the boiling point of water at 760 mm pressure is taken as 100 °C. The interval between these two fixed points is ...
