Re: Keep the Heat B/Thermodynamics C

So it ended-up going off pretty much without a hitch. Measured losses from my preheated volumetric flasks into the student's beakers were a consistent 10C. I heard from two DivC teams that that was consistent with their experiments, and they were able to very closely predict the final outcome. I end...
