Can heat transfer in a vacuum
WebRadiation differs from Conduction and Convection heat t transfer mechanisms, in the sense that it does not require the presence of a material medium to occur. Energy transfer by radiation occurs at the speed of light and suffers no attenuation in vacuum. Radiation can occur between two bodies separated by a medium colder than both bodies. WebJan 15, 2024 · But radiation — heat transfer via electromagnetic waves — can occur across a vacuum. In fact, that’s how the sun warms Earth. Now “quantum mechanics …
