How Efficient is a Laboratory Burner in Heating Water?
Michael P. Jansen
Cresent School, 2365 Bayview Avenue, Willowdale, ON, Canada M2L 1A2
Cover
February 1997
Vol. 74 No. 2
p. 213
Abstract
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. Extensive pre- and post- laboratory questions (and answers) are included.
