Measure mass(m) of water in the calorimeter.
Set the apparatus.Record the initial temperature of the water (q1). Pass steam through the tube and record the
final temperature of the water (q2) after a time(t).
Measure the length(L) of tubing beneath
the water surface, and measure also the internal and external diameters of the
tubing and hence find the internal and external radii (r and R).
