WebAnswer (1 of 5): The obvious way heat in a near vacuum is radiation. That is how the sun manages to radiate its heat! But of course the sun is extremely hot and big so dissipates a lot of energy…. about 4 x 10^26 watts! There is no conduction as there are nothing to conduct through… there is no ...
WebTherefore, radiation heat transfer is more efficient in a vacuum. In the case of a gas (e.g., air), energy can be slightly absorbed or reflected by air molecules and the balance is transmitted. For liquid medium, most of the radiation is absorbed is a thin layer close to the solid surface and nothing is transmitted [2] . hcs200 formWeb7 de jul. de 2024 · Advertisement Heat transfer by conduction and convection works by particles colliding and transferring energy, as there are no particles in a vacuum heat transfer can only occur by radiation.
