(xi) Which furnace can be used to get temperature above `3000^@ C` ?

Options

A. Blast furnace
B. Reverberatory furnace
C. Arc furnace
D. None of the above

Answer

To answer the question "Which furnace can be used to get temperature above 3000°C?", we can follow these steps:

### Step 1: Understand the Requirement
The question asks for a type of furnace that can achieve temperatures exceeding 3000°C.

**Hint:** Identify the key temperature requirement in the question.

### Step 2: Identify Types of Furnaces
There are various types of furnaces used in industrial processes, including:
- Electric arc furnaces
- Blast furnaces
- Induction furnaces
- Resistance furnaces

**Hint:** Consider the characteristics of each type of furnace and their temperature capabilities.

### Step 3: Research Temperature Capabilities
Among these furnaces, electric arc furnaces are known for their ability to reach very high temperatures. They operate by creating an electric arc between electrodes, which generates intense heat.

**Hint:** Look for specific temperature ranges associated with different furnace types.

### Step 4: Confirm the Electric Arc Furnace
Electric arc furnaces can easily exceed temperatures of 3000°C due to the high resistance of the materials used and the continuous flow of electricity. This makes them suitable for processes that require such high temperatures.

**Hint:** Focus on the mechanism of how electric arc furnaces generate heat.

### Step 5: Conclusion
Based on the information gathered, the furnace that can be used to achieve temperatures above 3000°C is the **electric arc furnace**.

**Final Answer:** Electric arc furnace.
