describe and sketch the plot of Temperature vs. Time for the evaporation of alcohol.
why does the plot appear as it does (explain any increases/decreases in temperature)?
Homework Answers
In order for a liquid to evaporate, the KE (hence velocity) of the molecules must be sufficient to escape the intermolecular forces at the surface of the liquid. ... So, ethanol would evaporate faster than water which means that ethanol has a more effective cooling effect than water.

PRE-LAB If you were to plot temperature (C) vs. time (minutes) for the following scenario, what would the general profile look like? What important information can be gleaned from your plot? 1) Solute "blue" is dissolved in a beaker of water at room temperature. 2) Room temperature is 22°C 3) 4) Solute "blue" takes about 3 minutes to dissolve. Upon dissolving the beaker warms up...to about 27°C. 5) The beaker containing the solution is then placed...
