Unformatted text preview: stearic acid cools down until it reaches about 50 °C. Note the temperature in your table when the first signs of solid formation are observed. 7. Plot a line graph of your results. Put time along the bottom and temperature up the side. Label your graph to show where stearic acid is a solid, a liquid or present in both states. Safety Wear eye protection. Data Time/min Temp/◦C Questions 1. What is the melting point of stearic acid? 2. What is the freezing point of stearic acid? 3. Why are there flat sections on your graph? Explain this in terms of the forces between particles. Home...
