FAQs on Rusting of Iron Video Lecture - Science Class 7
| 1. What is rusting of iron? |  |
Ans. Rusting of iron is a chemical process in which iron reacts with oxygen and moisture in the presence of air or water to form a reddish-brown substance called rust. It is a common phenomenon that deteriorates the appearance and structural integrity of iron objects.
| 2. Why does iron rust? | |
Ans. Iron rusts due to a process known as oxidation. When iron comes into contact with oxygen and moisture, it undergoes a chemical reaction in which the iron atoms lose electrons, resulting in the formation of iron oxide or rust. This process is accelerated in the presence of salt or acids.
| 3. How does rusting affect the properties of iron? | |
Ans. Rusting significantly affects the properties of iron. It weakens the metal by causing it to corrode and gradually disintegrate. The rust layer formed on iron surfaces is porous, brittle, and non-adherent, leading to a loss of strength, durability, and structural integrity. It also alters the appearance of iron objects, making them look dull and unsightly.
| 4. Can rusting be prevented? | |
Ans. Rusting can be prevented or minimized through various methods. Applying a protective coating such as paint or oil on the iron surface creates a barrier between the metal and moisture, preventing direct contact. Galvanization, where a layer of zinc is applied to the iron, can also provide protection. Another method is using sacrificial anodes, such as zinc or magnesium, that corrode instead of the iron. Regular cleaning, drying, and storing iron objects in a dry environment can also help prevent rusting.
| 5. What are the implications of rusting in everyday life? | |
Ans. Rusting has several implications in everyday life. It can lead to the deterioration of infrastructure, such as bridges and buildings, as their iron components weaken and lose structural integrity. Rusting of vehicles can impact their performance and safety. Additionally, rusting of household items like kitchen utensils and appliances can make them unusable and aesthetically unappealing. Therefore, understanding rusting and taking preventive measures is essential to maintain the longevity and functionality of iron-based objects.
