2. Explain the differences in the difference in temperature of these substances as they evaporated. Explain your results in terms of intermolecular forces.
A larger differences in temperature means that more of the substance was able to evaporate. This means that the intermolecular forces are weak and readily break.
3. Explain the difference in evaporation of methanol, ethanol, and n-butanol. Explain your results in terms of intermolecular forces.
Methanol has the highest change in temperature, ethanol has the second highest, and n-butanol had the lowest. This means methane had the most evaporation with the weakest intermolecular forces, while ethanol had the less evaporations, and n-butanol had the least evaporation with the strongest intermolecular forces.
4. Explain how the number of OH groups in the substances tested affects the ability of the tested compounds to evaporate. Explain your results in terms of intermolecular forces.
The more OH in a compound, the more hydrogen bonds. This means that it is harder to break the bonds and have the substance evaporate which is why Glycerins temperature went up.
