Heating rubber with sulphur is known as

Options

A. galvanisation
B. bessmerisation
C. vulcanisation
D. sulphonation .

Answer

**Step-by-Step Solution:**

1. **Understanding the Process**: The question asks about the process that occurs when rubber is heated with sulfur. This is a specific chemical process that alters the properties of rubber.

2. **Identifying the Term**: The process of heating rubber with sulfur is known as "vulcanization." This term is crucial in the context of rubber processing and is widely recognized in chemistry and materials science.

3. **Explaining Vulcanization**: Vulcanization is a chemical process that involves the cross-linking of rubber molecules through the addition of sulfur. This process enhances the rubber's physical properties.

4. **Benefits of Vulcanization**: The vulcanization process improves various physical properties of rubber, such as:
- Increased strength and durability
- Enhanced resistance to heat, oxidation, and chemicals
- Improved elasticity and flexibility
- Water repellent properties

5. **Conclusion**: Therefore, the correct answer to the question is that heating rubber with sulfur is known as vulcanization.

**Final Answer**: Heating rubber with sulfur is known as vulcanization.
