Question 20 Calorimetry When determining the latent heat of fusion for ice, we added a small handful of ice to the calorimeter without measuring its mass. This is fine because: Owe can deduce the added mass of ice at the end of the trial O the system loses heat to the surroundings O the equilibrium temperature of the system is arranged to be near room temperature O we do not need the mass of the ice, since latent heat is per kg anyways Question 21 Calorimetry In both experiments, we tried to make it so that the system's T happened to be around room temperature. Why is that? O To avoid getting burned O to facilitate heat exchanges within the system. O To reduce heat exchanges with the environment (at room temperature). O Because the thermometer could only register temperatures around room temperature.
