Answer:

Well the freezing point of #"ethyl alcohol"# is #-114# #""^@C#....

Explanation:

And the sublimation point of #"carbon dioxide"# is #-78.5# #""^@C#....

And thus #"ethyl alcohol"# melts at a lower temperature than that at which dry ice sublimes............I can't help you too much with temperatures that use the #"Fahrenheit scale"#.
