| 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
it evaporated there would be 1 inch of salt left. |
| 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. |
