  • What Is the Melting Point of Water?

    The melting point and freezing point of water ideally are the same, especially if there are gas bubbles in water, but if the water is free of nucleating points, water can supercool all the way down to −42 °C (−43.6 °F, 231 K) before freezing. So, in some cases, the melting point of water is considerably higher than its freezing point.

  • Difference Between Polar and Nonpolar Molecules

    Polar compounds show higher melting points and boiling points comparative to non-polar compounds with similar molecular masses. Energy should be supplied to break intermolecular bonds. Hence, melting points and boiling points are high. This results in low vapour pressure, and rate of evaporation is lower than that of non-polar molecules.
