What is the minimum amount of energy that must be removed to produce solid ethyl alcohol?

Question

A beaker contains 190 mL of ethyl alcohol at 23.0 degrees C. What is the minimum amount of energy that must be removed to produce solid ethyl alcohol?

Answer 1

You need to know the specific heat capacity of ethyl alcohol (2.46 J/g/C), the freezing point (-114.3) and the specific latent heat of fusion (108J/g) and the density of liquid ethyl alcohol (0.789 g/cm³) so you can work out how many grams you have.

So now you have enough information to do your homework.
