petrushka.googol Posted April 5, 2015 Share Posted April 5, 2015 We all know that water has maximum density at 4 degree C. What molecular property of water can explain this ? Link to comment Share on other sites More sharing options...
fiveworlds Posted April 5, 2015 Share Posted April 5, 2015 The melting point of ice is 0 °C (32 °F, 273.15 K) at standard pressure, however, pure liquid water can be supercooled well below that temperature without freezing if the liquid is not mechanically disturbed. It can remain in a fluid state down to its homogeneous nucleation point of approximately 231 K (−42 °C). http://en.wikipedia.org/wiki/Properties_of_water Link to comment Share on other sites More sharing options...
mathematic Posted April 5, 2015 Share Posted April 5, 2015 We all know that water has maximum density at 4 degree C. What molecular property of water can explain this ? Without knowing specifics, it seems that water molecules, when forming a crystal lattice, are farther apart than when free floating. Link to comment Share on other sites More sharing options...
