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.
