Optical interference measures evaporation rates of alkanes and alcohols on glass, suggesting differences based on molecular properties.
Evaporation of volatile liquids is a fascinating process that easily draws student interest because of its apparent simplicity. Why certain liquids evaporate faster than others can be explained by concepts that are introduced in general chemistry and physical chemistry, such as molecular geometries, dispersion forces and hydrogen bonding. The measurements of evaporation rates of liquids from ordinary glass surface were accomplished by a simple method based on optical interference.
