Question
Chapter 3.3, Problem 4E
a)
Interpretation Introduction
Interpretation:Reason for melting point to be melting range should be determined. Also, its measurement not as single temperature should be explained.
Concept introduction:Melting point is temperature that involves conversion of substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.
b)
Interpretation Introduction
Interpretation:Whether melting point exits theoretically or not should be determined.
Concept introduction:Melting point is temperature that involves conversion of substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.

heat, justify (prove) your chosen phase.
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. !t 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 until ethanol reaches 80 °C.
4. Label "Melting" where this takes piace.
5. Label "Vaporization" where this takes place.
6. Label "Phase Change" where a phase change occurs.
7. Indicate where ethanol is only a SOLID, only a LIQUID, and only a GAS.
8. Of the three phases, label which phase has: Weakest IMF (intermolecular force), Strongest
IMF, and Medium IMF.
