What is done to stop bridges from rusting?
Metal comes in contact with oxygen. That's the main reason that many mechanics wipe down their older metal tools with oil (WD-40). The coat of oil prevents air from contacting the metal. That's why they spend much more than $100,000 to paint a bridge. The coat of paint saves them. H2O, water, has the same effect on metal.
How does torsion effect a bridge?
There are 3 ways to prevent rusting A. Plate the metal with another metal, expensive. B. Paint or coat the metal with a chemical that prevents the metal from getting wet. C. Chemically treat the metal so it can only rust a little and it cannot rust through. Depending on what you are working with would determines the method you use.
What is a monolithic metal?
A monolithic metal is a single metal mass of any shape or form. It is not comprised of multiple metal types, or even multiple spatially distinct quantities of the same metal. An example would be a single cube of iron, or a sheet of aluminum. That is the basic premise.
What is galvanized iron pipe?
It is a metal pipe that was used before PVC and cpvc. I hate it, it know from closing shut whicjlh in turn well cause little to no water pressure. If ya go it, get it replaced. If you don't you'll be taking drip drop showers. <><><> Steel pipe coated with zinc metal (that is the galvinized part) which delays rusting.
Why are iron objects generally coated?
To prevent it from rusting.
What is an example of a metal corroding?
Rusting
Is rusting an example of physical or chemical change?
Rusting is the oxidation of a metal and is an example of a chemical change.
What are some physical changes when rusty metal is an example?
what are some physical changes when rusting metal is an example
The rusting of metal is an example of what change?
Is an example of chemical change, reacting to air
Is rusting an example of chemical change?
yes , in this change any metal converts to its oxide.
What example of a metal is rust proof?
Stainless steel is an example of a metal that is rust-proof. It contains chromium, which forms a protective layer on the surface of the metal that prevents it from rusting.
Is rusting a metal physical change?
Metal rusting (corrosion) is a chemical change.
What is the color change when metal rust?
It depends on what metal is 'rusting'.
Why the rusting of an iron bar decreases the strength of the bar?
When rusting occurs, some of the outer metal converts to a crumbly iron oxide that doesn't have the same strength as the metal. The deeper the rusting goes into the metal , the weaker the bar will become.

Is a car rusting a physical reaction?
Nope, chemical. Metal combines with oxygen to form whatever-metal oxide. example: Iron+oxygen=Iron oxide/rust
What example is rusting?
