Question
Reactions are classified as either exothermic or endothermic. Exothermic reactions feel hot (e.g., a burning campfire), whereas endothermic reactions feel cool (e.g. squeezing an instant cold pack). A thermometer measures the temperature of the surroundings in a calorimeter to determine the amount of energy being transferred by the system. Water molecules speed up when they gain heat and slow down when they lose heat; note that you can track both the cold and hot water molecules in the simulation based on the shade of red of the larger central oxygen atom by checking the box labeled Show microscopic view. Select the Experiment tab in the simulation, and then click Run Demonstration. When observing the simulation, pay particular attention to the temperature change and movement of the molecules by clicking Show microscopic view when HCl and NaOH neutralize each other in the fourth experiment. Use your observations to complete the following sentences. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. ▸ View Available Hint(s) Reset Help only water In the demonstration, observe what happens when substances at different temperatures are mixed.
