Evaporation, that is a transformation of a liquid into a gas, occurs at every temperature at which the given substance is liquid. The rate of evaporation (which could be defined as a mass of a liquid evaporated in a unit of time) depends on many different parameters - the temperature of the liquid, the pressure of the vapours above its surface, its surface area, the presence of flow on the .

The MSDS HyperGlossary: Evaporation Rate

The MSDS HyperGlossary: Evaporation Rate

Safety Data Sheets: An evaporation rate is the rate at which a material will vaporize (evaporate, change from liquid to vapor) compared to the rate of vaporization of a specific known material. This quantity is a ratio, therefore it is unitless. General usage: The mass of material that evaporates from a surface per unit time (examples: 3 grams per square meter per hour, 1 inch per acre per month).

Does Cooking Alcohol Really Burn It All Off? - Chowhound

Oct 01, 2007 · The answer is no. It's true that alcohol boils at a much lower temperature than water (173 degrees Fahrenheit compared with 212 degrees Fahrenheit), so in a sauce, for example, the alcohol will begin to evaporate before the water does. But simply heating the alcohol (or any other cooking liquid, for that matter) will not make it all evaporate.

This lack of cohesion between carbon atoms allows alcohol molecules to move past each other relatively easily, while water's strong internal attraction creates a resistance to evaporation. This is why water remains liquid from 0 up to 100 degrees Celsius, while most compounds have a much narrower thermal range for their liquid phases.
