Thermal Energy
| Term | Definition |
|---|---|
| temperature | a measure of the average value of the kinetic energy of the molecules in a substance; more kinetic energy means higher temperature |
| thermal energy | the sum of the kinetic and potential energy of all the molecules in an object |
| heat | the transfer of thermal energy from one object to another |
| conduction | transfer of thermal energy that occurs when the particles in a material collide with neighboring particles |
| radiation | transfer of thermal energy that occurs when energy is transferred by electromagnetic waves |
| convection | transfer of thermal energy by the movement of atoms or molecules from one part of a material to another part of the same material |
| conductor | any material that easily transfers thermal energy |
| specific heat | the amount of energy needed to raise the temperature of 1 kg of the material by 1 degree C |
| thermal pollution | an increase in the temperature of a body of water caused by adding warmer water |
| refrigerator | a heat mover that absorbs thermal energy inside it and release the thermal energy to the outside of it |
| air conditioner | moves thermal energy from inside a house to the outside of the house |
| heat pump | moves thermal energy either from outside to inside or from inside to outside |
| 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 from warmer to cooler until both reach the same temperature |
