SEP Interpret Data Look at the diagram. Imagine the following scenario: A factory where rock salt is kept in its liquid state loses power. The vat that contains the liquid rock salt begins to cool. The factory manager measures the temperature after 1 hour and again after 3 hours. Both readings show that the temperature of the salt is 801°C. What would you expect to see in the vat after 2 hours? Explain why you would expect to see this. Hint: Why would the temperature remain the same for 2 hours?
