Answer» tion:________________AIR do not havefixed MELTING and boiling point.________________The boiling point of a substance is where the liquid phase changes into GAS phase. The melting point of a substance is where the solid phase changes into the liquid phase. Since AIR is a MIXTURE of GASES, so, all the different gases have different melting and boiling points. So, air has no boiling point and it also has no melting point. ________________ |
