Experiment 25 calorimetry pre lab answers.
Water has a greater specific heat capacity because the temperature of the water only changed by 5.06 °C, unlike the copper's change of 54.94 °C. The water resisted temperature change more than the copper. 1. Predict: In the Gizmo warm-up, you saw how 200 g of 90 °C copper transfers heat to 200 g of 30.0 °C water. A.

Formal Lab Report: Experiment 25 Calorimetry Priscilla Rangel CHEM 1411-Abstract The main purpose of the Calorimetry experiment is to measure the enthalpy, specific heat capacity, of substances using a calorimeter. Within physical reactions there is a transfer of heat that can be released as an exothermic reaction, or absorbed as an endothermic ... The first experiment was using 0.5M of NaOH and HCl. At first, the temperature increase from 28C° to 29 C° and it stays constant for about 90 seconds. It starts to decrease to 28 C° after about a minute. The same situation also applies to the second and third experiment. For the second experiment, 1M of NaOH and HCl and 2M for the
