    Water adhesion: does not wet wax paper, but wets glass, towel, celery (capillary action).
    Boats float by diaplacing water with large surface area.
  1. colloid: haze/smog; milk is liqui/liquid colloid
  2. pH: potential Hydrogen; logarithm scale
  3. Carbonic acid buffer: If blood basic (low H+): more bicarbonate ions, more CO2 from lungs.
    If acid: pant to remove acid.
    Buffer: ratio of CO2 to HCO3-(bicarbonate ion); H+ increase -> HCO3- decrease, but there is large HCO3-.
  4. Tornado develops from thunderstorms, cool air overrides layer of warm air.
    Hurricane (tropical cyclone) rotate around area of low atmospheric pressure, warm sea, cool atmosphere, 10 degrees from equator.
  5. Evaporative Cooler quiet, low power in dry climates. compressor cause pressure changes between 2 compartments, pump refrigerant into cooled compartment (evaporator coil): evaporate, in the condenser the refrigerant vapor is compressed, condensing into liquid.
  6. Downburst: rain evaporates, endothermic, cool air sinks.
