An unknown sample was known to be either cinnamic acid(m.p 133 centigrade),urea(m.p 133-135C), or malonic acid(135-136C).Given a sample of the unknown and samples of each to these three compounds,briefly indicate how you could establish the identity of the unknown through m.p determination alone.

NB: For you critics out there, I have an answer(idea). just wanted to get more views as I could be wrong. I try very hard to do my assignments without having to disturb other people. So be lenient with any negative comments or more, if you don't want to answer, pls do not criticise.

Picture the scene. It's a hot summer's day. You're at work, You have an Orange, Mango and Apricot smoothie in your desk which is probably warmer than it should be. When you open it BOOM smoothie shoots up, even hits the ceiling (and specks are still visible). How can this happen?
