WebI would say the first point to stress here is that heat by definition is the transfer of energy. 'Heat loss' can occur via convection, conduction or radiation. Clearly, the first two can be essentially reduced to zero by surrounding your coffee (or whatever) with a perfect vacuum. Creating a perfect vacuum is pretty much impossible though. Webheat is the ramdomized (i.e. neglecting bulk flows) energy of motion in any material (including, for instance, photon gases). Any vacuum that we can make or have access too includes a small amount of matter, and the temperature of that stuff can be measured. WebAboutTranscript.

WebSolution. In a vacuum, heat is transferred by radiation. In radiation, heat is transferred in the form of electromagnetic waves, which require no medium to propagate . In conduction , heat is transferred from particle to particle , in vacuum there are no particles to transfer the heat , so conduction cannot transfer heat in vacuum . WebHeat does transfer through a vacuum, through a process called radiation (hot objects glow, but they may be glowing below the human range of vision, like in the infrared). Convection is a process where material flows around, and that material can carry heat with it. Since a vacuum has no material, there's no convection.
