thermal energy can be transfered by raditiaon
All objects transfer thermal energy by infrared radiation. The colder an object is, the more infrared radiation it gives off.
Conduction and convection do not need moving particles to transfer the thermal energy, but radiation does.
The heat an object contains is the amount of its thermal energy, measured in joules or J.
A thermometer is used to measure the temperature of an object
The temperature of an object is to do with how hot or cold it is, measured in degrees Celsius.
