The temperature of a reaction was monitored with an thermometer that is reported to have precision of 20.2 K (uniform distribution). If we used this thermometer to monitor the temperature change in a particular exothermic reaction, what is expanded uncertainty (use coverage factor k = 2) in the net temperature change for the following measurements: Temperature before reaction starts = 296.2 K Temperature after reaction is finished = 305.6 K Net temperature change = 9.4 K. Expanded uncertainty at the 95% confidence interval level (k = 2) = ? (include unit!) Answer: 0.3K

Anna was asked to identify and explain if the equation CO2 (l) → CO2 (g) was an endothermic or exothermic reaction. However she got it wrong. What is her error and what should the answer have been? Anna's statement: The equation is an exothermic reaction because the energy is released from liquid CO2 to the surroundings to become gaseous CO2 causing the molecules to slow down.
