What is heavy water? Does it occur naturally? Unusual properties of fluids include viscosity. Ketchup is a non- Newtonian fluid. Define a Newtonian fluid and a non-Newtonian fluid and explain why shaking a ketchup bottle helps it to flow and how ...
Like many other miracle materials, PFTE doesn't occur naturally: it has to be specially made in a chemical plant. Its discovery was a wonderful fluke—a laboratory accident that happened back in the 1930s. Since then, PTFE has been used on everything from waterproof clothing and Moon-...
How does aluminum get into groundwater? How does groundwater become polluted? Can groundwater get polluted by sewage, and if so, how? How can pollutants enter groundwater? How does water enter the groundwater system? How does groundwater accumulate?
The media and the government would have the public believe that an aluminum plane can pierce into a building ringed with steel columns, and after cutting through those columns, continuing to cut through even thicker columns in the core of the building. Below are examples of what happens to a ...

You’ll get that if you opt for one that has a piston made from anodized aluminum and a billet frame. Don’t even bother getting one made from plastic. Blow-off valves release excess pressure, but how can it do that if the pressure melts or cracks the plastic? When choosing the qualit...
Were you to see a plane flying overhead, you"d look up at its contrail and pity those poor people shrieking through the sky in a cramped aluminum tube. They will arrive days before you, sure. But they will have missed out on the wonders of a journey where there is no choice but to...
of fluoridation, while hydrofluorosilic acid is used in the majority of municipal fluoridation procedures. Fluoridation occurs naturally in some areas; indeed, it was from observations of a community drinking naturally fluoridated water that the benefits of fluoride in dental health we...
Bronze does not rust for the same reason as aluminum. It has a negligible amount of iron. Therefore, no iron oxide, or rust, can form. 4. Copper Copper does not rust; however, it can corrode. Copper is naturally brown and turns a shade of bright green as it corrodes. While some co...
