Challenge Question 1"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 filled a glass full of water from the Great Salt Lake, when
evaporated there would be 1 inch of salt left.
|True||False||(8) Sea water is slightly more basic (the pH value is higher) than
natural fresh water.
|True||False||(9) Raindrops are tear-shaped.|
|True||False||(10) Water boils quicker at Denver, Co. than at the beach.|
