heat transfers
science
| Question | Answer |
|---|---|
| Conduction | Transfer of thermal energy that occurs in solids liquids and gasses when two substances of different temperatures touch |
| conductor | A substance that allows the flow of electric charge or transfers thermal energy through matter |
| 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 tempatures |
| 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 gas also known as phases |
| radiation | The transfer of energy by the movement of electromagnetic waves or subtonic 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 |
