How do we prevent Rusting of Iron ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Rusting**: Rusting is a chemical process that occurs when iron reacts with oxygen and moisture in the environment, forming iron oxide (rust). To prevent rusting, we need to stop this reaction from occurring.

2. **Painting**: One effective method to prevent rusting is by painting the surface of iron. The paint acts as a barrier between the iron and the moisture in the air, thus preventing oxidation.

3. **Oiling and Greasing**: Another method is to apply oil or grease on the surface of iron. Similar to paint, oil and grease create a protective layer that prevents moisture from coming into contact with the iron.
