Challenge Question #3
"What are some of the physical and chemical properties of water?"
Water is more than just plain old water -- it actually has some very unusual properties. It would be boring if I just told you that water is wet and clear. So, instead, here are some "maybe true/maybe false" water properties. See if you know the real water facts.
True
False
(1) Water contracts (gets smaller) when it freezes.
True
False
(2) Water has a high surface tension.
True
False
(3) Condensation is water coming out of the air.
True
False
(4) More things can be dissolved in sulfuric acid than in water.
True
False
(5) Rainwater is the purest form of water.
True
False
(6) It takes more energy to heat water at room temperature to 212
o
F
than it does to change 212
o
F water to steam.
True
False
(7) If you evaporate an 8-inch glass full of water from the Great Salt Lake
(with a salinity of about 20% by weight), you will end up
with about 1 inch of salt.
True
False
(8) Sea water is slightly more basic (the pH value is higher) than most
natural fresh water.
True
False
(9) Raindrops are tear-shaped.
True
False
(10) Water boils quicker at Denver, Co. than at the beach.
