Intermolecular Forces Lab Report

In the experiment 1 of intermolecular forces via evaporation, groups were challenged to gain a better understanding of the molecular forces in alkanes and alcohols while also exploring the impact of molar mass on intermolecular forces. Before starting, it must be understood that evaporation is an endothermic process. Substances with weak intermolecular forces will experience a greater temperature drop. Strong intermolecular forces will not experience a great temperature change. Because of the key statements listed, the group predicted that alcohols would experience little temperature change due to the strong intermolecular forces within them.
There will three sets of data presented, scatter plots will also be presented showing the relationship between molar mass and boiling point as well as temperature change. The graphs will be able to be

The temperature probe was connected to the LabQuest pro. After, string was cut and a piece of filter paper was placed on the tip of the temperature probe. The string was used to tie the filter paper to the tip of the temperature probe. The probe was then placed in a container of liquid based on its group. Alkanes: Pentane, Hexane, Heptane; Alcohols: Methanol, Ethanol, 1-Propanol, 2-Propanol, 1-Butanol; Misc: Water, Acetone. The probe was let to soak in the liquid for thirty seconds. The date analysis was started after thirty seconds and the probe was left in the liquid for five seconds to establish a baseline. After the baseline was established, the probe was pulled out and taped to the table with the end of the probe facing out of the table. The data collection should continue until the graph reaches a absolute minimum. Using the statistics option in the LabQuest probe, a change in temperature will be calculated for each trial. Two trials for each liquid will be run. Molar mass, boiling point will be found using outside
