what is the melting and boiling point of water?

    Hydrogen gas, being the lightest and smallest molecule in the list, has the lowest melting point ( −259°C or 14.15 K or −434°F) and boiling point ( −253°C or 20.15 K or −423°F). Similarly, of the second row compounds with hydrogen, methane (CH 4 ) has the lowest melting and boiling points. However, water does not follow this trend. Its melting point is 0°C or 32°F. Its boiling point is 100°C or 212°F. Compared to the other molecules around it or its heavier cousin, hydrogen sulphide (H 2 S), water has melting and boiling points that are anomalously high. This is due to the fact that the hydrogen bonds between water molecules must be broken for a phase transition to occur. The extra energy required results in more heat being necessary and a higher temperature.

    Water freezes at 0 degrees C and boils at 100 degrees C.
