Question

25. What is rusting? Write some methods to avoid rusting?​

Answer 1

Rusting is the corrosion of iron metal
It happens because when iron is kept in the open it reacts with the water vapour in air to form ferric oxide which is a corroding material
Fe+H2O+O2-----> Fe2O3

Some ways to prevent rusting are-
1.Galvanisation
2.Painting
3.Oiling/greasing
