Burning of the candle is a.......... change.

Options

A. Physical
B. Chemical
C. Both (A) and (B)
D. None of them

Answer

To determine what type of change occurs when a candle burns, we can analyze the process step by step.

### Step-by-Step Solution:

1. **Identify the Components of a Candle**: A candle primarily consists of wax, which is the main substance that burns when the candle is lit.

**Hint**: Think about what materials make up a candle and their properties.

2. **Understand the Burning Process**: When a candle is lit, the heat from the flame causes the wax to melt. This is the initial stage of the burning process.

**Hint**: Consider what happens to the solid wax when it is exposed to heat.

3. **Observe the Physical Change**: As the wax melts from solid to liquid, we observe a physical change. The wax retains its chemical properties even though its state has changed.

**Hint**: Remember that physical changes involve changes in state or appearance without altering the substance's chemical composition.

4. **Recognize the Chemical Change**: When the wax continues to burn, it undergoes a chemical reaction with oxygen in the air, producing heat, light, carbon dioxide, and water vapor. This process is a chemical change because new substances are formed.

**Hint**: Think about what happens during combustion and the products that result from burning.

5. **Conclusion**: Since both physical and chemical changes occur during the burning of a candle (melting of wax is a physical change, and combustion is a chemical change), we conclude that burning of a candle is both a physical and a chemical change.

**Hint**: Look for options that indicate both types of changes when answering the question.

### Final Answer:
Burning of a candle is a **both physical and chemical change**.
