Physics 212 Lecture: "Heat and Temperature." Dec 15, 1997

Heat is a measure of the internal energy of materials
Temperature is commonly measured with three different scales: Fahrenheit, Celsius, and Kelvin
The Kelvin scale starts at "absolute zero"
Materials expand or contract as they change temperature
Under some circumstances, the amount of expansion or contraction is linearly proportional to the change in temperature

This lecture discusses material in Chapter 12 of Cutnell and Johnson.
