| A | B |
|---|
| heat | KE of molecules |
| convection | heat transfer in gases & liquids |
| conduction | heat transfer- direct contact |
| radiation | heat tranfer-waves-through vacuum of space |
| insulator | slows down heat transfer |
| conductor | allows heat to transfer easily |
| temperature | measurement of heat |
| Kelvin | absolute zero temp. scale |
| Celsius | scale used in most of world |
| Fahrenheit | scale used in US |
| matter | anything w/ mass & volume |
| density | amount of mass per unit volume |
| solid | molecules move slowly/packed tight |
| liquid | molecules more free/ flow/ more KE |
| gas | molecules move very freely/much KE/can be compressed |
| boiling | liquid-gas phase change |
| condensation | gas-liquid phase change |
| freezing | liquid-solid phase change |
| melting | solid-liquid phase change |
| sublimation | solid-gas or gas-solid phase change |
