### Temperature

Measure of the average kinetic energy of the individual particles

### Farenheit

tempurature scale on which water freezes at 32 degrees and boils at 212 degrees

### Celsius

Metric unit for measuring temperature; On this scale water freezes at zero and boils at 100.

### Kelvin

SI unit for temperature; On this scale water freezes at 273 and boils at 373

### Absolute zero

The coldest temperature possible, 0 deg Kelvin, that can be reached. Particles have no kinetic energy. Degrees same as on Centigrade Scale.

### Thermal energy

the total kinetic and potential energy of all the particles in a substance.

### Freezing

the change in state from a liquid to a solid

### Boiling

the application of heat to change something from a liquid to a gas

### Heat

gain heat or get hot.

### Conduction

Molecule to molecule transfer of heat

### Convection

Transfer of heat by fluid movement or liquids

### Convection current

a current caused by the rising of heated fluid and sinking of cooled fluid

Transfer of energy that by electromagnetic waves

### Conductor

a device designed to transmit electricity, heat, etc.

### Insulator

A material that does not allow heat or electrons to move through it easily. Examples: styrofoam, paper

### Specific heat

The amount of heat required to raise the temperature of 1kg of a substance 1 degree K
