What is the causes rust?

Answer 1

Rust is a chemical reaction to the surfaces of iron or steel becoming damp. When iron or steel get wet, the surface reacts with oxygen in the air and the water (usually rainfall) causing the metal to rust.

Answer 2

Rust is caused when any corrosive metal[mostly iron] is affected by moisture.This causes the metal to oxidise[combine with oxygen from the water] and become a metallic oxide,which appears in a typical maroonish color and is called as rust.

Answer 3

There are many factors involved which effect the rate of rusting for a given metal. The factors without which rusting would not occur are exposure of the metal to water and oxygen.

When these are both present rusting is likely to occur.

Factors which increase the rate of rusting:

Higher temperature

High water salinity

Higher atmospheric pressure

Painting the metal prevents it from rusting by isolating it from oxygen and water.

Biological Corrosion is made from living organisms, and living cells and bacteria. The cells are made up into 2 catorgories, Fungi and Bacteria cells.

Rust is the product of the reaction between Iron and Oxygen

Answer 4

Rust is caused by the oxidation of iron or steel when exposed to oxygen and moisture. This chemical reaction forms iron oxide, which weakens the material and gives it the characteristic red-brown color. Ensuring proper coating, maintenance, and protection against water and air can help prevent rust from forming.
