Heats of mixing

Abstract
(2) There were rather large heat exchanges between the "mixing vessel" and the "reference vessel" caused by conduction along the thermopile between the two vessels. (3) There was necessarily a heat effect due to breaking the glass seal which initially separated the two liquids. This effect was usually small but since no two seals were identical it was not reproducible. (4) The quantity of mercury in the calorimeter (about 350 g), and hence the heat capacity (about 50 JrC), were larger than desirable. These disadvantages have been largely overcome in the new calorimeter described below. In particular:
