Temperature change for an exothermic reaction
« on: October 24, 2012, 12:23:27 PM »
Will the recorded temperature change for an exothermic reaction performed in a glass calorimeter be greater or less than that in a styrofoam coffee cup calorimeter? Assume glass to be a better conductor of heat than styrofoam.

explanation please?

Hint: content of calorimeter always tries to equalize the temperature with surroundings.

I should imagine that the glass will conduct heat away more than the styrofoam does so it will record less of a heat increase in the surroundings for the same exothermic reaction.

Or am I looking at this too simplistically?

So I submitted some answer I guessed, but I still don't get why my book doesn't explain simply what does it mean to be a "better conductor of heat".. can someone please explain it to me in laymans terms?
