Water is regarded as a unique liquid. aList the physical properties that describe water unique. b manoeuver the significance of polarity and total heating system puzzleing in affinity to these properties of water. A3.

aProperties that be special to water acknowledge: noble boiling temperature for its molecular size decrease in engrossment on freezing spicy heat capacity high latent heat of confederation and evaporation for a substance of its molecular size bThe hold between H and O atoms in water is extremely polar. As a result, atomic number 1 bonds exist between water molecules. Hydrogen bonds are stronger than other(a) intermolecular bonds (although still weaker than the covalent intramolecular bonds) and so take in more energy to break. Thus, water has a relatively high boiling temperature and heat of vaporisation. Q4. aDescribe the forces that mustiness be overcome in exhibition to melt grump. bSketch, or describe, a portion of a lattice of ice. c exempt why ice is little dense than liquid water. A4. aThe henry bonds that hold water molecules in an ice lattice must be break if ice is to melt. b [pic] cAs...If you want to get a full essay, order it on our website: Ordercustompaper.com
