The lead of lead pencils melts at

Options

A. `2000^(@)C`
B. `350^(@)C`
C. `3170^(@)C`
D. `75^(@)C`

Explanation

To determine the melting point of the lead in lead pencils, we can follow these steps:

### Step 1: Identify the Composition of Pencil Lead
The lead in pencils is not actually lead (the metal) but is primarily made of graphite, which is an allotropic form of carbon.

**Hint:** Remember that pencil lead is commonly referred to as graphite, not the metal lead.

### Step 2: Understand Graphite's Properties
Graphite is known for its unique properties, including its high melting point. It is used in various applications due to its ability to withstand high temperatures.

**Hint:** Graphite is a form of carbon, and its properties differ significantly from those of metallic lead.

### Step 3: Research the Melting Point of Graphite
The melting point of graphite is typically reported to be around 3000 degrees Celsius. However, it can vary slightly depending on the specific form and purity of the graphite.

**Hint:** Look for reliable sources or textbooks that provide the melting point of graphite to confirm the temperature range.

### Step 4: Conclude the Melting Point
Based on the information gathered, the melting point of the lead in pencils (graphite) is approximately 3100 degrees Celsius.

**Hint:** When answering questions about melting points, always consider the range provided and select the most accurate option.

### Final Answer
The lead of lead pencils melts at approximately 3100 degrees Celsius.
