When a candle burns, both physical and chemical changes take place. Identify these changes. Give another example of a familiar process in which both the chemical and physical changes take place.

Explanation

### Step-by-Step Solution

1. **Understanding Physical and Chemical Changes**:
- Physical changes are changes that affect the form of a chemical substance, but not its chemical composition. These changes are usually reversible. For example, melting, freezing, and dissolving.
- Chemical changes involve a transformation that alters the chemical composition of a substance, resulting in the formation of new substances. These changes are typically irreversible.

2. **Identifying Changes in a Burning Candle**:
- **Physical Change**: When a candle burns, the wax (which is solid) melts into liquid wax. This melting process is a physical change because the wax is still the same substance, just in a different state (solid to liquid).
