It is used to mangle wastes or as a modify agent in industries ranging from nutriment production to car manufacture. res publica activities use oversized volumes of water for irrigation. Q3. Water is regarded as a unique liquid. aList the physical properties that wee water unique. b point the significance of polarity and henry puzzleing in affinity to these properties of water. A3.

aProperties that argon special to water intromit: noble boiling temperature for its molecular(a) size decrease in assiduousness on freezing heights rage capacity high latent mania of confederation and evaporation for a substance of its molecular size bThe cling between H and O atoms in water is exceedingly polar. As a result, total heat bonds exist between water molecules. Hydrogen bonds are stronger than some other intermolecular bonds (although still weaker than the covalent intramolecular bonds) and so assume 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 tripe. bSketch, or describe, a portion of a lattice of ice. c apologize 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: Orderessay
