__________of coal is a process in which coal is heated strongly at a temperature of `1000^(@)C` in the absence of air

Options

A. Carboniation
B. Destructive distillation
C. Mining
D. Metalling the road

Answer

To solve the question, we need to identify the process described in the statement. Here’s a step-by-step breakdown:

### Step 1: Understand the Process
The question states that coal is heated strongly at a temperature of `1000°C` in the absence of air. This indicates that the process involves heating coal without allowing oxygen to enter.

**Hint:** Think about what happens to organic materials when they are heated without oxygen.

### Step 2: Identify the Name of the Process
When coal is heated in the absence of air, it undergoes a specific chemical process. This process is known for breaking down the coal into various components, including gases, liquids, and solid residues.

**Hint:** Recall the term used for heating substances to break them down, particularly in the absence of air.

### Step 3: Define the Process
The process of heating coal strongly in the absence of air is called **destructive distillation**. During destructive distillation, coal is converted into coke, coal gas, and coal tar, among other products.

**Hint:** Consider what the term "destructive" implies about the nature of the process.

### Final Answer
The answer to the question is: **Destructive distillation** of coal is a process in which coal is heated strongly at a temperature of `1000°C` in the absence of air.

### Summary of Steps:
1. Understand the heating process without air.
2. Identify the name of the process.
3. Define the process as destructive distillation.
