mallebility and corrosion define the terms
Answers
Answer:
It is the property of metal in which metals can be drawn into thin sheets when hammered. ... Corrosion :- It is also the property at metal in which it get react with moisture or oxygen to form oxide.
Answer:
corrosion is one of the most common phenomena that we observe in our daily lives. You must have noticed that some objects made of iron are covered with some orange or reddish-brown coloured layer at some point in time. The formation of this layer is the result of a chemical process known as rusting, which is a form of corrosion.
Corrosion can be defined as the process through which refined metals are converted into more stable compounds such as metal oxides, metal sulfides, or metal hydroxides. The rusting of iron involves the formation of iron oxides via the action of atmospheric moisture and oxygen. Corrosion is usually an undesirable phenomenon since it negatively affects the desirable properties of the metal. For example, iron is known to have good tensile strength and rigidity (especially alloyed with a few other elements). However, when subjected to rusting, iron objects become brittle, flaky, and structurally unsound. Corrosion can be classified as an electrochemical process since it usually involves redox reactions between the metal and certain atmospheric agents such as water, oxygen, sulphur dioxide, etc.
If we look at the science behind corrosion then we can say that it is a spontaneous/ irreversible process wherein the metals turn into a much stable chemical compound like oxides, sulphides, hydroxides, etc. We shall delve deeper into the concept of corrosion and understand its different factors including its meaning, types, prevention and more in this lesson.
