For our second lab we used dry ice to look at different states of matter like we did with the oobleck lab but with the dry ice lab we focused more on how things change states of matter and how different pressures and temperatures can change a materials state of matter. To show us these changes Andrew placed a piece of dry ice in a tube that can be closed off and allow the gas let off from the dry ice to pressurize the tube creating the solid dry ice to change to liquid form. When the pressure was let out from the tube the dry ice shot out and solidified forming a snow like substance.
After andrew showed us this, he gave each of us our own piece and allowed us to experiment any way we liked . With my piece I played it into a glass of water so I can see the gas come off of the piece of dry ice. After the piece was placed into the water gas bubbles were coming off of the dry ice which were actually CO2 bubbles that created a steamy effect at the top of the cup, this steam was more dense than the rooms air so it looked like it could be poured out of the cup.
To show how much CO2 was being let off of the dry ice we placed a 1 centimeter piece into a balloon and tied it off to see how far it expanded.
