Webb5 jan. 2024 · depends on wheather explanation: It depends on the temperature of each system (not just the temperature difference since in the case of electromagnetic radiation radiant power is proportional to temperature to the 4th power). It depends on whether the transfer of energy is through conduction, convection or radiation. Advertisement WebbTherefore Radiation Heat is more efficient in a vacuum. An example of radiation heat is the heat transfer from the sun to earth due to electromagnetic waves through vacuum space. But when the sun radiation enters the earth’s atmosphere, its impact starts reducing due to air, gas, water, and dust particles present in the earth’s atmosphere.
