 *These results are likely to be anomalous as the experiment was not entirely successful at this time. Lots of CO2 escaped.
Hopefully this table makes more sense then my last lot of  carbon dioxide results.
I've only managed to test my hypothesis at two different temperatures so far. I intend to continue tomorrow with the water at 60 degrees Celsius. I'm also having trouble calculating the volume of CO2  per 100mL as I have to include the water in the beehive shelf in the equation. However, I don't need to calculate this for every result, I just need to check if they fit with the expected volume/10mL.

I may need to look at my results for 50 and 48 degrees, they should be more than those at 25 degrees not less.  I also need to reconsider my method for heating the water. It takes too long and it is almost impossible to keep the water at a consistent temperature. This may be contributing to my anomalous results.
