Phase Change Lab
In this lab, we had to demonstrate the different phase changes of water. Each group was assigned to perform a different phase change and after completing our lab, we each presented our observations and data that we collected. My lab partner and I performed the process of melting, in which we recorded the temperature of ice and placed it on a hot plate and recorded the temperature as the heat melted the ice. We collected the temperatures throughout the process and recorded them onto a data table and graph which depicted the amount of energy added. We presented our data to our groups and put them together to show all of the phase changes together including melting, freezing, evaporation and vaporization.
Airbag Activity
In this lab, the purpose was to stimulate a proper airbag. To accomplish this, we created our own procedure and we calculated the correct amount of baking soda to react with vinegar by using stoichiometry. If calculated correctly, the reaction would result in an ideally inflated bag. My partner and I were able to obtain an ideally inflated bag which means we had completed our calculations correctly.
