What are some of the physical and chemical properties of water?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 212o F
than it does to change 212o 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.
