1. Temperature, Heat and Thermal Expansion

2. Internal Energy

3. Thermal Energy

4. Temperature Measures the Thermal Energy of Material
Related to the average KE of the atoms/molecules

5. Temperature Scales
Fahrenheit
Celsius
Kelvin

7. Objects that exchange thermal energy are said to be in thermal contact

8. Heat
Energy transferred between two objects in thermal contact that are at different temperatures

10. Thermal Equilibrium
Objects in Thermal Contact will reach the same temperature – The objects are then in Thermal Equilibrium.

11. Zeroth Law of Thermodynamics
If A and B are objects in thermal equilibrium with a third object C, then A and B are in thermal equilibrium with each other

12. Methods of Heat Transfer
Conduction
Convection
Radiation

14. Conduction
Heat

16. Convection
Air

18. Radiation

19. Thermal Expansion
As the temperature of a material increases, the average molecular speed increases which in turn generally increases the volume of the material

21. Linear Expansion

22. Linear Expansion in 2D
After
Before

23. Expansion of a Hole

24. Area Expansion

25. Volume Expansion
Regular Solid
