Why can heat radiation travel through a vacuum? - Quora

WebIf heat can travel through a vacuum (radiation), then how is heat conserved in a thermal flask where the vacuum blocks the heat? If you define thermal radiation as heat (I don’t) then it can travel through a vacuum. If you define heat this way then all electromagnetic radiation from VLF radio waves to gamma rays are heat. WebJul 21, 2024 · Convection likewise requires the presence of a gas that can develop convection currents. Since a vacuum does not contain any gas, heat transfer by convection does not occur in vacuum...

WebHeat transfer in vacuum takes place by the means of heat transfer process called RADIATION. Radiation does not require the presence of a material medium to take place. In fact ,energy transfer by radiation is fastest (at the speed of light) and it suffers no attenuation in vacuum. Webdue to radiation. Answer 4: It's true that heat cannot conduct through vacuum, since conduction only happens when molecules collide. In fact, thermos containers and some insulated windows trap a layer of vacuum between two walls (perhaps glass or metal) to reduce heat transfer by conduction. But even if you could prevent all heat
