Melting point of liquid 1 (non-supercooled):47.1 degrees Celsius
Melting point of liquid 2 (supercooled): 47.3 degrees Celsius
Part 2: Based upon your notes and data from part 2, answer the following questions. Show all work as necessary. 8. On the attached graph of your data from part 2, indicate the region where the liquid solid phase transition is taking place for each sample. Explain your choice. 9. What are the freezing points (°C) for the non-supercooled and supercooled samples? Comment on these results. Non-supercooled: Supercooled: 10. Did the temperature of the supercooled liquid rise or fall upon addition of a seed crystal? Explain this observation. 11. Was this crystallization an exo- or endothermic process? Explain your choice. 12. What would the final temperature of both test tubes be if we let them sit for 8 hours?
