Every substance has different physical properties. Some substances melt at room temperature, while others, like certain metals, need extreme amounts of heat. This also goes for freezing points, where some are naturally solids at room temperature, while others are naturally liquids or gaseous. A freezing point is the same thing as a melting point—it is the temperature at which a solid changes its state to a liquid and vice versa. So, what happens to the physical properties of certain substances when they are mixed together? In this case, what happens to the freezing point of water when it is mixed with carbon dioxide? The goal of this experiment is to demonstrate the differences in physical properties of different substances by instantly freezing club soda.
