Water Properties
P Polarity
Unequal electron sharing creates partial charges enabling hydrogen bonding.
Hydrogen bonds forming throughout the liquid.
C Cohesion & Surface Tension
Hydrogen bonds create cohesion between molecules and surface tension.
Surface tension supports the water strider.
H High Heat Capacity
Water absorbs/releases heat with minimal temperature change.
Lake absorbing heat slowly, moderating temps.
V Heat of Vaporization
Evaporation requires significant energy, enabling cooling.
Minimal evaporation at surface.
D Ice Density
Stable hydrogen bonds form a fixed lattice structure, making ice less dense so it floats.
Water in liquid form throughout.
