    I need help on thinking more factors that can affect my results for measuring enthalpy change (using a polystyrene cup as a colorimeter.............) involving solid potassium hydrogen carbonate reacting with HCl acid

    - Heat loss to environment instead of just the solvent surrounding
    - Inaccuracies of the apparatus

    Improvement: Use bomb calorimeter.. (not too sure how it works.. can someone please help explain?)

    Not sure what more there is to it though.. That's too short! Please help, thanks!

    Another thing. My chem teacher told us to measure the max and min. temp of the temperature of the solution during the reaction.

    But the other chem teacher said measuring the temperature of the solution every 30 minutes then extrapolate the temperature to measure the temperature change.

    Which method is better and why?
