Question

Direction: Graph the heating curve of ethanol using the information given. Check off each item as you add additional information to your graph so that none is missed.

Background information of Ethanol:

Boiling Point = 78 0C

Melting Point = -114 0C

Starting Temperature = -120 0C

After two minutes, frozen cold ethanol starts to melt. It takes two minutes to melt completely.
After eight more minutes, it begins to boil. It boils for six minutes.
Heat is added for two more minutes until ethanol reaches 80 0C.
Label “melting” where this takes place.
Label “vaporization” where this takes place.
Label “phase change” where a phase change occurs.
Indicate where ethanol is only a SOLID, only a LIQUID, and only a GAS.
Of the three phases, label which phase has: weakest IMF, strongest IMF, and medium IMF.
