An Inexpensive Solution Calorimeter Emma Kavanagh, Sam Mindel, Giles Robertson, and D. E. Peter Hughes
Describes the construction of a simple solution calorimeter, using a miniature bead thermistor as a temperature-sensing element, that has a response time of a few seconds and made it possible to carry out a thermometric reaction in under a minute.

The q/T Paradox: Which "Contains More Heat", a Cup of Coffee at 95°C or a Liter of Icewater? Ed Vitz and Michael J. Schuman
In this demonstration, heat is removed from 10 cm3 of water at ~95C and 42 cm3 of water at ~0C by adding each to a measured sample of liquid nitrogen. The heat removed from the water boils the N2(l), and the quantity of liquid nitrogen that is evaporated by boiling is determined. The quantity of heat that was absorbed is calculated from the heat of vaporization of liquid nitrogen and found to be about 10,000 J in the case of the hot water and 25,000 J in the case of the icewater.
