Question

Read the sentences and answer the questions that follow . Yash lives in Mangalore , a coastal town of Karnataka. He observed that the body of his bicycle rusts very frequently. 1. What could be the reason for Yash's observation? 2. What must Yash do to keep his bicycle rust-free and in good condition?

Answer 1

1. Yash's bicycle gets frequently rusted because of the moisture present in the coastal areas.

2. To protect the bicycle from rusting, Yash can apply paint on the bicycle.

Explanation:

Moisture (water) in air rusts the body of metal. Therefore, the body of metal like iron can be painted with zinc to stop or inhibits rusting.

The reaction of iron with moisture is the process of oxidation. As iron gets oxidized, the metal losses its quality.

So, in order to save the material from rusting, the metals are coated with zinc. The process is known as Galvanization.

Zinc is reacts slower than iron as per the reactivity series of metals and therefore can be used for keeping the bicycle in good condition without getting oxidized.
