Can heat transfer in a vacuum

WebMar 30, 2016 · Heat transfer is proportional to the difference of the temperatures to the power of 4. This means that it's not just the difference in temperature, but amplified by the sum of their temperatures and the sum of the square of their temperatures. Thus heat transfer in a vacuum is partially proportional (conductive), and partially non linear. WebAnswer (1 of 3): Radiation exchange always occurs between a substance and the environment, if the two are at different temperatures. This is the only practical way to lose (or gain) heat in space. Evaporation (from a liquid surface) or sublimation (from a solid surface) can also occur in a “vacu...
