Thermal & Kinetic Energy
| Question | Answer |
|---|---|
| conduction | transfer of heat within a substance or between two substances in direct contact |
| convection | transfer of heat due to the flow of fluids (liquids or gases) |
| heat | transfer of thermal energy within or between substances due to a difference in temperatures |
| radiation | transfer of heat through air and empty space in the form of waves |
| system | area and/or group that is identified in order to determine the interactions |
| thermal energy | total kinetic energy of the particles in a substance; it can be transferred from one location or substance to another as heat |
| transfer | move from one place or object to another |
| temperature | average kinetic energy of the particles in a substance; measured with a thermometer |
| thermal energy | total kinetic energy of the particles in a substance; can be transferred from one location or substance to another as heat |
| thermal equilibrium | state in which all objects within a system have reached the same temperature and there is no overall transfer of heat between them |
| kinetic energy | energy of motion |
| particle | small unit of matter |
