Calorimetry calculations often assume no heat exchange between the calorimeter and the surroundings, but in real life this heat transfer does in fact occur. Correctly complete the following statements regarding the results of actual calorimetry experiments. Calcium oxide reacts with water in a coffee cup calorimeter and the temperature of the solution increases by 24.1oC. In this experiment, heat flows --_________ (into OR out of) the calorimeter, the temperature change that would occur in a perfectly insulated calorimeter is --_________ (larger than OR smaller than OR the same as) the measured temperature change, and the actual enthalpy change is --_________ (larger than OR smaller than OR the same as) the experimentally determined enthalpy change for the reaction. Barium hydroxide reacts with ammonium thiocyanate in a coffee cup calorimeter and the temperature of the solution decreases by 34.5oC. In this experiment, heat flows --________ (into OR out of) the calorimeter, the temperature change that would occur in a perfectly insulated calorimeter is --_________ (larger than OR smaller than OR the same as )the measured temperature change, and the actual enthalpy change is --_________ (larger than OR smaller than OR the same as) the experimentally determined enthalpy change for the reaction.
