Some physical properties of water are: pure water is colourless, odourless and tasteless liquid, it freezes at 0oC and boils at 100oC under 1 atm pressure. Water is a non-conductor of electricity and heat. The density of the water at 4oC is 1 g/ml. Water is neutral to litmus.
Structure of water
Water has three dimensional structure in which central oxygen is bonded to two hydrogen atom.The hybridization of oxygen issp3 .
Hydrogen bonding in water and ice
In water hydrogen bonds are formed between two Hydrogen (H) and electronegative (O) Oxygen atom, the bonding is intra molecular Hydrogen bonding because it is formed between the hydrogen and oxygen atom which is present in same molecule.
Boiling point of water
Water (H2O) is a polar, universal solvent. Liquid at room temperature and boils at 1000C.
Freezing point of water
The freezing point of water is 32 degrees Fahrenheit, or zero degrees Celsius. The freezing temperature of water also equals the melting temperature of ice.
Uses of water
Water is used for photosynthesis by plants, drinking, bathing, washing, cooking by humans and also in industries.
surface tension of water
The cohesive force between liquid molecules is responsible for the phenomenon known as surface tension. The molecules at the surface of water do not have other water molecules on all sides of them and hence they cohere more strongly to those directly associated with them,
