Label This Diagram

a - boiling water

b - metal shavings

c - boiling tube in clamp

d - insulation

e - thermometer

f - lid

g - metal calorimeter

h - cold water

Avoid splashing when shavings are added

Define 2 precautions that are associated with this experiment • 2

Room temperature equal to initial and final temperatures to cancel out errors

Write out the formula associated with this experiment

m (s) c (s) temp change (s) = m (w) c (w) temp change (w+c) + m (c) c (c) temp change (w+c)
