Why are the melting and boiling points of heavy water more than those of ordinary water? |
| Answer» Solution :The molecular masss of heavy WATER `(D_(2)0)` is more than that of ordinary water `(H_(2)O)`. As a result there is a grater DEGREE of association of molecules in heavy water than in ordinary water. This results in greater melting and BOILING POINTS as compared to ordinary water. | |
