In the beginning of the day we talked about phase changes, how changing pressure and/or temperature can change matter into something entirely different, for example liquid into gas.
Dry Ice in a balloon:
Dry Ice is made of pressurized carbon dioxide. As an experiment we put two cubic centimeters of dry ice in a balloon and tied it off. Over time we watched the balloon inflate with carbon dioxide. After he dry ice melted in the balloon we measured the balloon it had grown to 1767.15cm^3. This experiment was to observe the volume change from solid to gas.
Dry ice and bubble soap:
Right when we put the dry ice into the water it began to smoke. It was rappidly changing into gas.
