Measuring CO2 pressure in a soda bottle

[chantybell]

Is it possible to test the CO2 pressure in a soda bottle as simple science project that can be done at home? What kind of apparatus is need? The original goal is to test if CO2 pressure changes at different temperatures. It would be helpful if anybody had any suggestions on how to go about performing this experiment.

Hi chantybell,

Sure it's possible. You'll just need some type of pressure gauge and a thermometer that will measure the respective properties. You may have to put the soda in a different container that has a proper fitting for the gauge and thermometer though.

A home improvement or hardware store will likely have an apparatus or at least the parts for you to make one as well as the pressure gauge and thermometer.

Good Luck!
