Document Summary
Expansion among freezing (only liquid that expands when frozen) Water is the only body that occupies more spaces when it becomes a solid. Versatility as a solvent (universal solvent) . Because of its polarity (xylem and phloem) Contributes to the transport of water and dissolved nutrients against gravity in plants. Water molecules are cohesive because of hydrogen bonds. Adhesion of water by hydrogen bonds to the molecules of cell walls help counter the. Possible because of the hydrogen bonds between water and the cell walls. Adhesion : the clinging of one substance to another (water sticking to a towel) downward pull of gravity temperature. Water absorbs heat from warmer air and releases stored heat to cooler air. Water can absorb/release a large amount of heat with only a . Kinetic energy : the energy of motion (anything that moves has ke); energy of molecules in motion (molecules are constantly moving)
