Can heat exist in a vacuum

WebJan 15, 2024 · A combination of vacuum and heat is used to reach the vapor pressure of water. This causes the water to boil into a gaseous state. For example, at atmospheric pressure 760 mm Hg (14.7 psi), water boils at 100°C (212°F). Under a vacuum of 150 mm Hg (2.89 psi), water boils at 60°C (140°F). The vacuum system, including pipe headed … WebAug 8, 2024 · Vacuum does not mean a space that is completely devoid of matter, dark matter, or photons. While a perfect vacuum makes for a very nice spherical cow assumption, no such space exists. While physicists do like their spherical cow assumptions, they also self-effacingly deride themselves for making those spherical cow assumptions.
