### Temperature

the AVERAGE kinetic energy of an object's particles due to non-directional motion at the atomic level

### Heat flow

always goes from hot to cold

### Conduction

the direct transfer of heat from one solid to another solid that it is touching

### Convection

the transfer of heat by the circulation or movement of a liquid or gas; heats evenly because of the fact that fluids can flow

the transfer of heat by rays or waves

### Conduction (examples)

stovetop, seat-warmer

### Convection (examples)

oven, blood (circulating), furnace

sun, heat lamp, microwave

32°F

212°F

373K

### Absolute Zero

the temperature at which particles stop moving entirely (impossible to actually reach)

### Heat

the TOTAL kinetic energy of an object's particles due to non-directional motion at the atomic level

C + 273 = K

### converting Fahrenheit to Kelvin

must convert to Celsius first, THEN to Kelvin

Kelvins

### Why do we have the Kelvin scale?

1) Absolute zero is zero
2) There are no negative temperatures

### specific heat

How hard it is to change the temperature of something.

### high specific heat

difficult to change the temperature

water

### low specific heat

easy to change the temperature

metal
