Kavanagh, Emma; Mindel, Sam; Robertson, Giles; Hughes, D. E. Peter – Journal of Chemical Education, 2008
We describe the construction of a simple solution calorimeter, using a miniature bead thermistor as a temperature-sensing element. This has a response time of a few seconds and made it possible to carry out a thermometric reaction in under a minute, which led to minimal heat losses. Small temperature changes of 1 K associated with enthalpies of…
