Imf and evaporation rate
WitrynaEvaporation occurs when the probe is removed from the liquid’s container (see figure 1). This evaporation is an endothermic process that results in a temperature decrease. The magnitude of a temperature decrease is related to the strength of intermolecular forces of attraction between molecules. WitrynaC. Evaporation Rate 3. Put two drops of acetone and two drops of ethanol on either end of a paper towel and observe their evaporation. D. Surface Tension 3. Get two dry …

Witrynathis problem wants us to rationalize why these different factors have on ah rapper of evaporation rates. And so first we have this I M f, which is inter molecular forces. And so if you have greater in molecular forces, so mawr attraction between the two molecules, you are going to have it. It's going to be much harder to evaporate, so harder to … Witryna18 sty 2002 · The evaporation of a sessile droplet with a pinned contact line is investigated experimentally, by analytic theory and by computation using the finite element method (FEM). Because of the low value of R2/Dtf = cv(1 − H)/ρ = 1.4 × 10-5, where R is the contact-line radius, D is the water vapor diffusivity, cv is the saturated …
