7PRACTICE PROBLEM
In a chemistry lab, a scientist continuously provides heat to an 800 g sample and records the temperature changes. The final phase change is complete at Q = 200 kJ and the data is presented in the graph as shown. Determine the i) heat of fusion and ii) heat of vaporization for the substance based on the experimental results.
