6 characteristics of water

specific heat
protects from rapid temperature loss, high so takes long to heat up, amount energy takes to raise 1g 1 degree c (4.2 joules)
heat of vaporization
evaporative cooling, high, pulls heat from body, keeps you cool
universal solvent
water both charges, solute being dissolves, solvent does dissolving, hydrophilic loves water (+/-), hydrophobic hates water (no charge), ampipathic (both)
cohesion and adhesion
cohesion water bond to water, adhesion water bond to anything else hydrophilic, capillary action both work to move water up tree roots
surface tension
hydrogen bonds give you surface tension, gives eco systems, water striders
insulator and density
ice less dense than water, insulates lakes, rigid hydrogen bonds
