1. Suppose you have 1.00 mol of liquid water at 0.0 C and add just enough heat to bring the temperature of the water to 100.0 °C, but no more heat is added. How much heat was added?

Heat Q = m·c·ΔT

Explanation: Mass of 1.00 mol water m= 18.016 g. Heat capacity of water is

c= 4.19 J/( g K) and change of temperature ΔT= 100 K

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
