Water
Properties of water
Polar Molecule
Strong intermolecular forces
Relatively high BP and MP
Hydrogen Bonded
High heat capacity
Universal solvent
Liquid water is more dense than solid water as solid water expands
V shape polar molecule
High surface tension due to hydrogenbonds
The ability of a liquid to push back on something
Covalently bonded
Capillary action
When water goes up a thin passage against the forces of gravity(occurs a lot in plants)
Adhesion and Cohesion
Adhesion is the attraction between water and other objects
Cohesion is the attraction between to or more water molecules due to there hydrogen bonding
When water is the solvent the solution is called aqueous (aq)
Earth relating to water
70% of the earth is made from water
Only 3% is drinkable
Only 1% is readily drinkable
Water is essential for photosynthesis
Essential for life as we know it
Water cycle
naturally found in all 3 states:
Gas
Liquid
Solid
Vaporisation (l) --> (g)
Fusion (s) --> (l)
Freezing (l) --> (s)
Formulas
Calculating heat capacity
Energy=Mass(m) x Specific heat capacity(c) x Change in temperature(T)
Calculating latent heat
heat energy in kJ(q)=number of mol(n) x latent heat value of fusion or vaporisation kJ/mol(L)
