Convection Heat transfer caused by the rising of hotter, less dense fluids and the falling of cooler, denser fluids
Energy The ability of a system to do work; required for changes to happen within a system
Heat Transfer The thermal energy exchange between two objects of different temperatures; energy moves in a predictable pattern from warmer sites to cooler sites until all sites have reached the same temperature
Kinetic Energy Energy of motion
Matter Anything that has volume and mass
States of Matter Distinct forms of matter known in everyday experience: solid, liquid, and gas; also referred to as phases
Radiation The transfer of energy by the movement of electromagnetic waves or subatomic particles
System A group of interacting, interrelated, or interdependent elements forming a complex whole
Temperature Average kinetic energy of all the particles in a material; measured by a thermometer in degrees (usually degrees Celsius or degrees Fahrenheit)
Thermal Energy The total kinetic (motion) energy of the tiny particles that make up matter; the faster the particles move, the warmer the matter becomes
