The metals are eaten away when they are exposed to water, oxygen and other chemicals. What is this process known as ?

Options

A. Oxidation
B. Corrosion
C. Galvanisation
D. Amalgamation

Explanation

**Step-by-Step Solution:**

1. **Understanding the Problem**: The question asks about the process in which metals are degraded when they come into contact with water, oxygen, and other chemicals.

2. **Identifying the Options**: The options provided are:
- A) Oxidation
- B) Corrosion
- C) Galvanization
- D) Amalgamation

3. **Analyzing Each Option**:
- **A) Oxidation**: This process involves the addition of oxygen or the removal of hydrogen from a substance. While metals can oxidize, this is not the specific term for the degradation caused by environmental factors.
- **B) Corrosion**: This is the correct term for the slow degradation of metals due to environmental factors such as water, oxygen, and chemicals. Corrosion leads to the deterioration of metals over time.
- **C) Galvanization**: This is a method used to protect metals from corrosion by coating them with a layer of zinc. It is not a process of degradation but rather a prevention method.
- **D) Amalgamation**: This refers to the process of mixing mercury with another metal to form an alloy. It is unrelated to the degradation of metals.

4. **Conclusion**: Based on the analysis, the correct answer is **B) Corrosion**. This term specifically describes the process of metals being eaten away due to exposure to various environmental factors.

**Final Answer**: The process is known as **Corrosion**.
