B. Creating a Heating Curve: Graph the heating curve of ethanol using the information given. Check off each box as you add additional information to your graph so that none is missed. Background Information on Ethanol: Boiling point = 60 °C Melting point = -105 °C Starting temperature = -120 °C 1. After two minutes, frozen cold ethanol starts to melt. It takes two minutes to melt completely. 2. After eight more minutes, it begins to boil. It boils for six minutes. 3. Heat is added for two more minutes unti! ethanol reaches 80 °C. 4. Label "Melting" where this takes place. 5. Label "Vaporization" where this takes place. 6. Label "Phase Change" where a phase change occurs. 7. Indicate where ethanol is only a SOLID, on!y a LIQUID, and only a GAS. 8. Of the three phases, label which phase has: Weakest IMF (intermolecular force), Strongest IMF, and Medium iMF.
