All objects transfer thermal energy by infrared radiation. The hotter an object is the more infrared radiation it gives off.
No particles are involved in radiation. This means that thermal energy transfer by radiation can even work in space.
Radiation is how we feel the heat of the sun. Infrared cameras give images even in the dark because they are detecting heat not visible light.
Temperature is the measure of energy per particle.
Energy is transferred by radiation.
Differences in temperature can lead to transfer of energy.
Energy can be transferred through conduction, convection and evaporation.
Insulation can reduce transfer of energy from hotter to colder objects.
