The melting point of 3 liquids are 280K , 320K, and 360k. The order of intermolecular force of attraction between these three liquid A,B,C are in the order BCA. label the B.P of each liquid
Greater the intermolecular force of attraction, high amount of energy (heat) will be required to overcome these attractions. As a result boiling and melting points will be higher.
Since in your question you have not mentioned that the order BCA is increasing or decreasing order of intermolecular forces, so I am assuming that it is increasing order that is B < C < A. Also boiling points are not given to label instead you have provided melting points..
However, Boiling point of B will be minimum and boiling point of A will be maximum. The boiling point of C will be intermediate of B and A.
