For each trial, enter the amount of heat lost by the calorimeter, qcalorimeter.

Be careful of the algebraic sign here and remember that the change in temperature is equal to the final temperature minus the initial temperature.

Report your answer using 4 digits. Note, this is 1 or 2 digits beyond the correct number of significant figures.
