Using the intermolecular bonding between H2O moleculesin it's two condensed phases (solid ice versus liquid water), explain the observed phenomenon that: 1) ice floats 2) ice formed in the crevices of a road or the granite face of a mountain is able to crack the road or cause boulders to break loose from mountain 3) given that the density of ice at 4 degrees C is 0.917 g/mL and that of sea water at 4 degrees C is 1.0278 g/mL, calculate the mass of liquid water (in metric tons) displaced by an iceberg that weighs 7.00 metric tons. Assume that 95% of the iceberg's volume is submerged under the surface of water. (1 metric ton = 1000 kg, exactly).
