Thermal energy Heat energy
Zeroth law "Thermal equilibrium" Objects in thermal equilibrium are the same temperature and don't transfer heat energy to each other.
The first law of Thermodynamics Energy and matter can never be created or destroyed.
The second law of Thermodynamics Everything starts wearing out, falling apart or decaying over time.
The third law of Thermodynamics The entropy of something approaches its minimum as it's cooled toward absolute zero.
Entropy A measure of disorder.
Heat Atoms in motion.
Heat source The item that is hotter.
Heat sink The item receiving the heat.
Radiation Energy that moves through space.
Convection Heat that is transferred in fluids,liquids, and gasses.
Sea breeze Air that is heated over the land rises, the air over the ocean rushes in to fill the empty space that the rising air left.
Land breeze Air that rises over the sea and the air from the land flow to replace it.
Conductor Moves things from one place to another.
Insulators If something does not transfer heat well
Combustion A Chemical process in which some material reacts quickly with oxygen to give off heat.
Fire Triangle Heat, fuel, and oxygen, we can have a fire.
Ignition temperature The temperature a substance must reach in order to ignite.
Temperature How active the molecules are in the substance.
Fahrenheit The classic English form of measuring things.
Celsius The world outside the United States use this system, which fits in with the metric system to measure temperature.
Kelvin Another form of measuring temperature that's used only by scientists.
Thermometers A measuring device that measures temperature because they are filled with matter, such as mercury or alcohol.
Thermal Expansion When things begin to heat up, they begin to expand.
