Metal is the only substance that can rust. Corrosion is a slow chemical change that occurs when a metal reacts with oxygen. The new substance is called a metal oxide. Iron reacts with oxygen to form iron oxide, also called rust. Aluminum reacts with oxygen to form aluminum oxide. A special alloy (including iron) can be used to coat a peice of metal and protect it from corrosion. The metal alloy will corrode quicker than the metal you are protecting.

∙ 13y agoRust is a product of oxidation. Oxidation occurs when an iron comes in contact with oxygen. Water (H2O) contains oxygen and so the iron becomes rusty. It can happen simply by staying outside too long.
All metals rust. What we look for, rust, is apparent as to how well the metal goes through a process called oxidation. When iron oxidizes it becomes rust (iron oxide). Some metals have atoms that are more interested in staying with their similar atoms. These metals won't oxidize as quickly. When they do, we call this tarnish. This is why gold, silver, or aluminum don't look like they've rusted when compared to iron. But that hazy kind of look that metals get over time is he surface layer rusting (tarnishing).

∙ 15y agobecasue they react more with oxygen and water (:

∙ 12y agoBecause there is more moisture in the air when it is warm, becuse of the humidity, and metal rusts faster with more moisture.

What must molecules do for matter to become warm?
They move faster & faster
What happens when cold and warm water mix?
When waters of different temperatures mix together, they tend to retain their temperatures. But the temperature of the two different temperatured waters combine to form a slightly warm water (only if the volume of both the waters is same). Overtime their temperatures become in proportion to the surroundings
When does diffusion occur quicker?
It happen more quickley at warm temperature.
What conditions are needed for rusting to take place?
Moist and sometimes warm environment. Also only certain kinds of metals or mixes of metals rust. For example, gold doesn't rust, but iron easily rusts.
Does ice melt faster in warm water salt water or vinegar water?
salt
What water will rust the fastest cold or hot water?
warm water will rust metal faster
Why should you never use metal for a birdhouse or bird bath?
Metal heats up and could be way too warm for the birds. And metal could rust and get holes in it.
Why does water cool faster in the beieging then at the end?
In the beginning of what ? At the end of what ?Do you mean "Why does hot water cool faster than cool water ?" ?Because the rate at which heat passes from a warm object to a cool objectdepends on the difference in their temperatures. So, as the warm objectbecomes less warm and the difference in their temperatures becomes smaller,the rate at which heat flows between them also becomes less.
Why would gases diffuse faster on a warm day than on a cold day?
The molecules of a gas move faster at higher temperatures, which therefore speeds up diffusion.
Do popsicles melt faster in warm or cold weather?
Faster in warm weather. Ambient temperature is what affects the melting point of frozen products. If you take a popsicle out of a -32F freezer into a room at 70F it will melt faster than taking it out into 50 degree F outdoor temperatures.
What type of bread molds faster?
whole wheat or white bread im trying to do my science fair project and i looked up that it can be whole wheat or white bread
Why does warm water evaporate faster then cold water?
At higher temperatures waer molecules at the surface of the liquid have more energy and is more simple to escape into atmosphere.
Why would a bicycle rust in warm places?
humidity
What is a warm front and what kind of weather does it bring?
Warm air, which brings warm temperatures.
What is the quaggas climate?
warm temperatures
What parts of a car can rust?
It rusts because of the oxygen present in atmosphere. Rust is iron oxide - where the iron in the steel has combined with oxygen. Preventing oxygen reaching the metal is the primary way to avoid rust, and this is done primarily with paints and other coatings.
How is grass growth and development influnced by temperature?
cold temperatures stall grass growth by freezing (or slowing the average energy of the molecules) of the plants water. Warm temperatures mean higher fluidity so easier nutrient transfer and faster growth.
