Today in class the students performed various experiments with dry ice to observe the effects of temperature and pressure on a substance's phase. We started by allowing dry ice to sublime inside of a sealed pipet to increase its pressure. By doing so, we eventually reached the triple point of carbon dioxide and were able to observe liquid CO2! We also observed the opposite effect of increasing the pressure on solid water and how it actually causes it to melt. We also observed how gas can be dissolved in a liquid through the pH change of adding carbon dioxide to water .
