front 1 ![]() Conduction | back 1 Transfer of thermal energy that occurs in solids, liquids, and gases when two substances of different temperatures touch |
front 2 ![]() Conductor | back 2 A substance that allows the flow of electrical charge or transfers thermal energy through matter. |
front 3 ![]() Convection | back 3 Heat transfer caused by the rising of hotter, less dense fluids and the falling of cooler, denser fluids. |
front 4 ![]() Energy | back 4 The ability of a system to do work; required for changes to happen within a system. |
front 5 ![]() Heat Transfer | back 5 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. |
front 6 ![]() Kinetic Energy | back 6 Energy of motion. |
front 7 ![]() Matter | back 7 Anything that has volume and mass |
front 8 ![]() States of Matter | back 8 Distinct forms of matter known in everyday experience; solid, liquid, and gas; also referred to as phases. |
front 9 ![]() System | back 9 A group of interacting, interrelated, or interdependent elements forming a complex whole. |
front 10 ![]() Temperature | back 10 Average kinetic energy of all the particles in a material; measured by a thermometer in degrees (usually degrees Celsius or degrees Fahrenheit) |
front 11 ![]() Thermal Energy | back 11 The total kinetic (motion) energy of the tiny particles that make up matter; the faster the particles move, the warmer the matter becomes. |
front 12 ![]() Radiation | back 12 The transfer of energy by the movement of electromagnetic waves or subatomic particles. |
