Term | Definition |
---|---|
Matter | Anything that takes up space and has mass. |
Solid | Matter with a definite shape and definite volume. |
Liquid | Matter that has a definite volume but no definite shape. |
Kinetic energy | energy an object has due to its motion |
Energy | the ability to do work or cause change |
Gas | Matter that does not have a definite shape or a definite volume. |
Thermal energy | The sum of the kinetic and potential energy of the particles in a material. |
Temperature | Measure of the average kinetic energy of the individual particles of a substance. |
Heat | Movement of thermal energy from a substance at a higher temperature to a substance at a lower temperature. |
Melting | Change of matter from a solid state to a liquid state. |
Freezing | Change of matter from a liquid state to a solid state. |
Vaporization | Change of matter from a liquid state to a gas. |
Condensation | Change of matter from a gas to a liquid state. |
Evaporation | Type of vaporization that occurs at the surface of a liquid as it enters the gaseous state. |
Pressure | Amount of force applied per unit area on an object's surface; SI unit is the Pascal (Pa). |
Buoyant force | Upward force exerted on an object immersed in a fluid. |
Sublimation | Change of matter from solid state to gas state. |
Density | Physical property of matter that can be found by dividing the matter's mass by its volume. |
Deposition | Change of matter from gas state to solid state |
Specific heat | the amount of heat required to raise the temperature of 1 gram of a substance by 1 degrees Celsius |
Ionization | Change of matter from gas to plasma state |
Recombination | Change of matter from plasma to gas state |
