1) Water has very high specific heat.
2) It expands when it freezes
3) ability to dissolve in ionic substances
4) Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.
1) Water molecules due to their high specific heat , undergo relatively less increase in temperature after absorbing heat. So they prevent their adjoining area to experience sharp increase in temperature.
2) Water is an example which expands on freezing. In it , large spaces are left between molecules when it cools. It happens because hydrogen bonds prevent any two molecules to come very close thereby creating gaps. This gap is filled up when ice melts , which results in overall reduction in volume of water.
3) Uneven distribution of charge results in water molecules becoming polar in nature . A polar substance can be dissolved in polar solvents only.
4) It is due to property of surface tension. Property of surface tension results due to molecules of water near the surface experiencing a net downward force due to hydrogen bonds . It is due to fewer hydrogen bonds made by them.
