Question

Rahul was a student of class 7. His father purchased a new bicycle for him on
his birthday. After few months, he found that the cycle chain and even the handle
gets rusted. His father advised him to apply a coating of paint to the cycle and not
to keep it in the open future.
a) Why his cycle gets rusted?

Answer 1

Answer:

Rahul’s cycle was kept in the open for a longer time. As air contains both oxygen and moisture. Thus, in the presence of oxygen and water, his cycle slowly gets rusted.

Iron(Fe) + Oxygen + Water →Rust (Iron oxide)
