3.1 Thermal Physics

3. Thermal energy transferred along substance without any bulk movement
4. Poor conductors
9. Amount of thermal energy needed to raise the temperature of a mass of one kilogram of a substance by one kelvin
11. Kinetic energy of a particle is proportional to the absolute temperature in Kelvin
15. Stage substance is in (i.e gas, liquid, solid)
16. Point of view of the system as a whole and how it interacts with its surroundings
18. When two objects reach the same temperature (2 words)
19. Average kinetic energy of the molecules in a substance
20. Basic SI unit for 'amount of substance'

1. Point of view of the inside of the system to see how component parts interact with each other
2. Gas One that follows the gas laws for all values P,V, and T
5. Thermal energy required to melt a unit mass of material at its melting point
6. Total kinetic energy of the molecules of a substance, plus any potential energy associated with forces between molecules
7. Gives molecules the force to have potential energy
8. Term for the change from liquid to gas
10. Law At constant V.=, P is directly proportional to T; P/T=constant
12. Zero -273 C or 0K
13. Theory that particles are constantly in random motion
14. Matter not involved in the transfer of thermal energy by radiation
17. Term for the change of phase from solid to liquid
