Temperature of Steam in an Espresso Machine - The Physics Factbook fermions, Furthermore, temperatures above 35C can begin to denature, or breakdown, enzymes, reducing metabolic function 18. (P.S.I.G.) In the gas form, water molecules are spread out and have a lot of room to move and get much hotter than the other two phases (liquid and ice). The unit of this scale is the degree Fahrenheit (F). Because a D-value can be determined at various temperatures, a subscript is used to designate the exposure temperature (i.e., D121C). Temperature Fahrenheit = (- 0.5o C)(1.80) + 32 Definition of Fahrenheit and Celsius . So to draw a conclusion, you could say steam is hotter than water except at 100C, at which point they are at the same level of hotness. It will just form at 100 degrees(just about to vaporize-saturated liquid, just about to condense-saturated vapor), but there is no limit for its temperature to rise. (A temperature of 0 may be forecast for a cold winter day in Michigan, while a temperature of 110 may be predicted for a hot summer day in Arizona.)
