JoinScience Sampler: Bubbles on a soda can: A demonstration of Charles’s Law
The bubbles-on-a-soda can activity is an illustration of Charles’ law, which states that for a fixed amount of gas, there is a direct relationship between the temperature of the gas and its volume. In other words, if the temperature of a fixed amount of gas increases, so does its volume. The opposite is true, as well: If the temperature of the gas decreases, the volume decreases. Your students will "bubble" forth with enthusiasm as they engage in this hands-on activity.
