Key Stage 3
Meaning
Heating is a way of transferring energy from one Energy Store into another through Conduction, Convection or Thermal Radiation.
About Heating
- Heating happens when two objects of different temperature are in contact with one another.
- Energy is transferred from the hotter to the cooler object until they reach 'Thermal Equilibrium' which means they are both at the same temperature.
- Heating transfers energy from the Thermal Energy Store of one object to the Thermal Energy Store of another object.
There are three ways that heating can occur:
- Thermal Conduction - Vibrating particles collide with other particles passing on their energy.
- Convection - Fluid at high temperature is less dense than fluid at low temperature so the high temperature fluid rises and the low temperature fluid sinks.
- Thermal Radiation - Objects can emit and absorb Thermal Radiation. The higher the temperature the more Thermal Radiation they emit.
