Water
adhesion: does not wet wax paper, but wets glass, towel, celery (capillary action).
Boats
float by diaplacing water with large surface area.
- colloid:
haze/smog; milk is liqui/liquid colloid
- pH: potential Hydrogen; logarithm scale
- 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-.
- 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.
- 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.
- Downburst:
rain evaporates, endothermic, cool air sinks.
