Procedure Collect Beakers of different Ethanol and Ethylene Glycol mixtures with ratios of 0: 100, 25:75, 50:50, 75:25, 100:0 percentages of mixture. Place dry ice in each beaker. For each mixture ratio use lab quest to determine the temperature and pressure of each mixture. Record all data and plot graph. Results The results of our experiment Showed that percentages with a higher Ethylene glycol content had a higher pressure, but lower temperature compared to the mixtures with higher Ethanol content.
In our lab we noticed accurate trends in reassure and temperature. We also observed that Ethanol had a lower pressure at 100%, than Ethylene Glycol at 100% As shown in the graphs below Discussion In out lab experiment for the most part we measured everything accurately when it came to recording temperature and pressure of the Ethanol and the Ethylene Glycol mixtures. The one thing that I did notice a trend in is the longer the dry ice sat in the mixtures compared to when it was first submerged the pressure and temperature changed relatively.
So I think in this experiment our calculations are if because we were measuring the pressure and temperature of the mixtures all at different times after the dry ice had been submerged into the mixtures. Conclusion In conclusion this lab indeed did show us trends of pressure and temperature that we should have seen. While pressure increases, temperature decreases, and when Pressure decreases temperature increases. And the overall trend indicated that ethylene Glycol has a higher pressure at 100% than Ethanol at 100%. Lab: How the Ideal Gas Law Applies to Real Physical Experiments By maidenhood’s
