Learn how to use a simple method to find the pressure inside bottles of soda pop. To do so, the temperature of the bottle, the mass of gas in the headspace of the bottle, and the volume of gas headspace are determined. Once these values are found, the ideal gas law is used to find the pressure inside the bottle. This video is great for teachers looking for a simple physics or chemistry activity that deals with the properties of gases or the ideal gas law (PV = nRT).
