In the process of destructive distillation, up to what temperation is coal heated?

Options

A. `100^(@)C`
B. `400^(@)C`
C. `1000^(@)C`
D. `2000^(@)C`

Answer

**Step-by-Step Solution:**

1. **Understanding Destructive Distillation**: Destructive distillation is a process where organic materials, such as coal, are heated in the absence of air. This prevents combustion and allows the material to break down into various components.

2. **Temperature Requirement**: During the process of destructive distillation of coal, it is heated to a high temperature.

3. **Specific Temperature for Coal**: According to the information provided, coal is heated to approximately **1000 degrees Celsius** during destructive distillation.

4. **Products of Destructive Distillation**: At this temperature, coal breaks down to form several products, including coke, coal gas, and coal tar.

5. **Conclusion**: Therefore, the temperature at which coal is heated in the process of destructive distillation is **1000 degrees Celsius**.

**Final Answer**: Coal is heated to **1000 degrees Celsius** during the process of destructive distillation.
