Temperature Scales
Want temperature scale where energy is proportional to T
Celsius scale is “arbitrary”  (Fahrenheit even more so)
0o C     = freezing point of water
100o C = boiling point of water
By experiment, available energy = 0 at “Absolute Zero” = –273oC  (-
459.7oF)
Define “Kelvin” scale with same step size as Celsius, but 0K = -273oC =
Absolute Zero
Use Kelvin Scale for most of work in this course
Available energy is proportional to T, making equations simple (really!
OK, simpler)
273K = freezing point of water
373K = boiling point of water
300K   approximately room temperature
