Heat energy we receive from the sun.

THERMAL ENERGY

The 4 special laws that deal with energy and all of matter.

LAWS OF THERMODYNAMICS

The study of thermal energy.

THERMODYNAMICS

There is no transfer of heat between two objects on thermal equilibrium.

ZEROTH LAW

Energy and matter can never be created or destroyed.

FIRST LAW OF THERMODYNAMICS

The universe is always becoming less and less disordered or organized.

SECOND LAW OF THERMODYNAMICS

A measure of disorder.

ENTROPY

The entropy of something approaches its minimum as it is cooled toward absolute zero.

THIRD LAW OF THERMODYNAMICS

Atoms in motion.

HEAT

The hotter item between heat source and heat sink.

HEAT SOURCE

The item receiving the heat.

HEAT SINK

Energy that moves through space.

RADIATION

Heat that moves through empty space.

RADIANT HEAT

Heat that transfers in liquids and gases.

CONVECTION

When air that’s heated over the land rises, the air over the ocean rushes in to fill the space that the air left.

SEA BREEZE

When air rises over the sea and air from land flows in to replace it.

LAND BREEZE

Occurs when the heat source and the heat sink are connected through matter.

CONDUCTION

A chemical process in which some material reacts quickly with oxygen to give off heat.

COMBUSTION

The things we need to have fire: heat, fuel, and oxygen.

FIRE TRIANGLE

A temperature at which something will light on fire.

IGNITION TEMPERATURE

Measures how active the molecules are in a substance.

TEMPERATURE

What Americans and some other countries use to measure temperature; water freezes at 32 degrees and boils at 212 degrees.

FAHRENHEIT

What everyone else measures temperature in; water freezes at 0 degrees and boils at 100 degrees.

CELSIUS

A form of measuring temperature only used by scientists, scales using the coldest temperature and the hottest temperature of an object.

KELVIN

When things heat up and they expand.

THERMAL EXPANSION
