Chapter 12, Problem 008 If a non-human civilization were to develop on Saturn's largest moon, Titan, its scientists might well develop a temperature scale based on the properties of methane which is much more abundant on the surface than water. Methane freezes at-182.6°C on Titan, and boils at-155.2°C, Taking the boiling point of methane as 100.0°M (degrees Methane) and its freezing point as 0°M, what temperature on the Methane scale corresponds to the absolute zero point of the Kelvin scale?...
