IB PHYSICS > PRACTICAL WORK > IB IA EXPERIMENTS [|IA criteria checklist.doc] - always a good idea to look at this before submitting your work. =PRACTICAL: Estimate of rate of heat loss of a boiling kettle=

APPARATUS:
Electric kettle, electric balance

PROCEDURE:
Boil the kettle for a short time while it is standing on an electric balance. Plot a graph of mass against time and use this to estimate the latent heat of vaporisation of steam. Compare this value to the known value and thus estimate the rate of heat loss of the kettle.

REPORT:
Table, graph, gradient of graph. See DCP criteria.
