Question

Radiation requires a heated liquid to transfer energy

Answer 1

true or false ???

Answer 2

Hello and welcome to Open Study!
I cannot give you the answer, but I can give you an explanation so you'll understand!

Radiation mode of heat transfer is energy propagation, transmitted by any object wich has a finite temperature to its surrounding. This transfer done without any medium, because the energy transmitted in the form of electromagnet mave. The total nett radiation affected by emissivity and diffusivity of the object and the temperature difference.
