Investigation of the effect of temperature on the rate of rust


Rusting is the corrosion of iron and readily occurs in the alloy steel. The formation of a reddish brown flakes which loosely adheres to the steel is called rust. Rust is formed when iron reacts with water and oxygen to form hydrated iron oxide also known as rust. There are factors that increase the rate of rust such as acid or salt which causes water to become a better electrolyte to help with the formation of rust.The aim of the project was to find out if the temperature affected the rate of rust. We approached this project using the experimentation method, Measure a function or relationship: Experimental research (II). Our hypothesis was that the higher the temperature, the lesser the rust formed. We proved our hypothesis wrong when we found out that room temperature was the best for rust formation. The applications of this finding would be that to slow down formation of rust, we should put it in a colder/ much hotter place.
