Question- I have an unknown Liquid which I need to find the melting point of. I'm thinking I need to crystallize it somehow, and then put the crystal in the melting point machine.

How would you go about doing this? Will simply putting it in an ice bath suffice for the crystalization process?

Provide me complete explanations of above question so I can get high score
