1. Physics 100 Chapt 9 Temperature & heat

2. Temperature scales Fahrenheit 212 F 32 F - 459 F room temp 27 C 300 K 80 F

3. Temperature  avg KE

4. Thermal atomic motion Heat energy = KE and PE associated with the random thermal motion of atoms Airsolid

5. Summary Heat is energy associated with random motion of atoms & molecules in material Temperature tells you the average “thermal” energy (including KE & PE) of atoms & molecules At absolute zero (T=0K, or -273C, or -459F) motion of atoms & molecules in material ceases.
