Heat in a vacuum
WebIn vacuum, boiling point is so low that water shouldn't need so much heat as it does in normal pressure, which means vapor actually takes more heat away under normal pressure than in vacuum, so water under normal pressure would be cooler? (I'm guessing) WebUniform temperatures in the range. 800–3,000 °C (1,500–5,400 °F) Commercially available vacuum pumping systems can reach vacuum levels as low as 1 × 10 −11 torrs (1.3 × …

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] .
