An Integrated-Circuit Temperature Sensor for Calorimetry and Differential Temperature Measurement Mark Muyskens
Application of an integrated-circuit (IC) temperature sensor which is easy-to-use, inexpensive, rugged, easily computer-interfacable and has good precision is described. The design, based on the National Semiconductor LM35 IC chip, avoids some of the difficulties associated with conventional sensors (thermocouples, thermistors, and platinum resistance thermometers) and a previously described IC sensor.

How Efficient is a Laboratory Burner in Heating Water? Michael P. Jansen
When a laboratory (or Bunsen) burner is used to heat water, all of the energy liberated by the burning fuel is not absorbed by the water. This article describes a procedure for determining the percentage efficiency of this common apparatus. This experiment is suitable for secondary school students who are familiar with stoichiometry , simple calorimetry, heats of reaction, collection of gas by downward displacement of water.
