Name DATA SHEET 13.2 Section Dato (continued Post-Lab Questions 1 Consider the surface tensions you determined in Table 13.12. How do they compare to the predictions you made in pre-lab question 1 in terms of relative intermolecular force strength? Are there any results that surprise you? 2 Assume that after you drew ethanol into the capillary tube for your first trial in Part B, you waited too long to measure the column height, and some of the ethanol evaporated without you realizing it. In your second trial, your finger broke the surface tension of the ethanol column, so a small amount wicked out onto your finger before you measured the column height. In your third trial, there were no errors. a How would the errors in Trial 1 and Trial 2 affect the average column height of ethanol you calculated? b How would the incorrect average column height for ethanol affect the value you calculated for the capillary tube radius? c How would the incorrect average column height affect the actual value for the capillary tube radius? d How would the incorrect value for the capillary tube radius affect the value you calculated for the surface tension of the remaining liquids? (Assume these column height measurements were error free.) e How would the incorrect value for the capillary tube radius affect the actual value of the surface tension of the remaining liquids
