Directions. Graph the heating curve of ethanol using the information given.

Background Information on Ethanol:

Boiling point: 60 degrees Celcius

Melting point: -105 degrees Celcius

Starting temperature: -120 degrees Celcius

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 until ethanol reaches 80 degrees 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, 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.
