Water has no taste, no color, no odor;
it cannot be defined, art relished while ever mysterious.
Not necessary to life, but rather life itself. It fills us with a
gratification that exceeds the delight of the senses.

Sand, and Stars, 1939
2. Water vapor is :
A. as dense as carbon dioxide
B. lighter than Helium
C. cooler than the
dew point of an air parcel
D. more buoyant than
E. heavier than air
3. Water is known as the universal
B. Thermal Interface
E. Toy for
4. At four degrees centigrade (4°
C) water expands on
C. Both A and B
D. Not at all,
water is uncompress able
5. Hot and cold water have
different properties. Which of these is NOT true:
as cold liquid water is
A . the speed
within it increases
conducts heat better
C. gasses become
liquid water is heated:
D. it shrinks
E. it becomes
easier to compress
6. Viscosity measures a fluid's
internal flow resistance. Water flows relatively easily in comparison
to olive oil.
Under 34° C , what happens to water's
viscous flow as pressure increases? It:
A. Does not change
until you get to exceedingly high pressures of over 400 atmospheres.
B. Becomes even
lower than normal
E. Becomes stickier
7. Heon Kang
and his colleagues in South Korea ran across Warm Ice
or frozen water at room temperature, serendipitously. What had they inadvertently done to crystalize water at their ambient
A. Increased the
salinity of the water abruptly.
B. Enclosed the a
sample in a diamond
anvil cell and increase the pressure to 200 Mpa.
C. Applied a
couple of million or so volts to the sample with a scanning
tunneling microscope (STM).
D. Exposed the
surface to near vacuum while examining the sample with neutron
E. Used a bench
Magnetic Resonance (NMR) machine.
8. In stratiform
and cumulus clouds,
airplanes often run into this form of water which consequently causes
problems with lift.
B. Diamond Dust
Most people have seen broken water pipes caused
by subzero temperatures. So they know that water unlike most other
liquids expands when frozen by about nine percent at sea level. How would that expansion ratio change if you increase atmospheric pressure?
the water that will ever be is,
