Develop and describe a method to predict the force exerted by the expelled CO2 on the system using Newton's second law. In the space below, describe your method. Don't take the measurements or calculations yet, just describe what you'll measure. Make sure you include a discussion of the sources of experimental uncertainty and how you'd minimize that uncertainty.

The amount of heat required to change liquid water to vapor at its boiling temperature is 2256 kj/kg. the amount of heat required to change liquid mercury to its vapor state at its boiling temperature is 295 kj/kg. one kg of each substance is currently at its boiling point. how will the amount of thermal energy required to change each substance from a liquid to a gas differ?
