Me and my girlfriend have been having a discussion for a whole day about whether or not fats are oils. We’ve googled it and the only facts we found is that fats are solids and oils are liquid, we also found that they are the same, we both agreed on that. But she also claims that oils are necessarily plant-based, which I don’t agree with.
She’s studying biology, and knows the chemistry and the proper names for things, while I have less scientific know-how, but know damn well you can use bacon fat as cooking oil. I don’t know if l’m right, moreover, I don’t know how to explain that she is wrong (if she is). Please help.

Yes. It has to do with polarity. A water molecule is electrically polar, it has a positive side an a negative side. Oils/fats are non-polar, they don’t really have a concentrated charge anywhere. That’s why you can’t dissolve oil in water and vice versa and that’s where we draw the line in chemistry.
