There are three
temperature scales in common usage:
The Fahrenheit Scale:
we are most familiar with this one
water freezes at 32 degrees F.
water boils at 212 degrees F.
when we cool to the absolute lowest temperature we
reach -459 degrees (this is referred to as Absolute Zero)
The Celsius Scale:
water freezes at 0 degrees C.
water boils at 100 degrees C.
Absolute Zero is at -273 degrees C.
The Kelvin Scale
Absolute Zero is 0 K
a temperature change of 1 degree K is the same as
a temperature change of 1 degree C.
water freezes (or melts) at 273 K
water boils at 373 K
The Kelvin is scale is the more useful scale for our course
since it refers to Absolute Zero in a direct way.
