Water is particularly complicated because of relative humidity, but it and wind and temperature have been investigated for reservoirs. Vapor pressure at some temperature can be a good indicator of evaporation rate, but a very strong factor in evaporation is wind, or blowing across the solvent surface.
Many tables of solvent characteristics do not include evaporation rate, but do show vapor pressure at room temperature, e.g. This time, or the rate for 90% evaporation, can be compared with another solvent under the same conditions.Įvaporation rate is a commonly listed on Safety Data Sheets, and in other tables, generally compared to butyl acetate or ether.
Pure compounds will have a fairly sharp disappearance and therefore a sharp time to evaporate mixtures like kerosene or gasoline will evaporate fast at first, then slower and slower. Another condition would be in a paint, where you desire a higher boiler to allow enough time to spread the paint without brush strokes.Ī practical way to compare evaporation rates of solvents is to put a small amount into a dish and weigh it as it evaporates. This chemlab 13 comparing rates of evaporation answers, as one of the most enthusiastic sellers here will totally be in the midst of the best options to review. One condition would be under vacuum in a rotary evaporator, to remove a low-boiling solvent to assist crystallization of a solute. What should be the criteria to compare evaporation rate of liquids at a given temperature?Įvaporation rates are used to compare solvents for different reasons and under various conditions. 2.1 Sharing Pizza: Comparing And Scaling Rates Comparing And Scaling 1 Investigation 2. If we consider intermolecular forces as the criterion, then the order of evaporation would be:īut part of intermolecular forces still act in vapour phase.
