Evaporation and Intermolecular Attrations

First thing we did was get probe 1 and probe 2, wrapped square pieces of filter paper and tightened them with rubber bands.  In the methanol container we put probe 1 in, then we placed probe 2 in the ethanol container. After them being in their for 45 seconds we immedietly taped them at the edge of the counter at 5 cm. Once they were nice and secured we observed and waited for the temperatures were at their lowest. We got the highest temp and the lowest temp and subtracted to figure out the change during evaporation. After the whole process we repeated it with the exact steps and recorded the data.
