Explain the difference between thermoplastic and thermosetting plastics.

Explanation

### Step-by-Step Solution

1. **Definition of Thermoplastics and Thermosetting Plastics**:
- **Thermoplastics**: These are plastics that can be melted and reshaped multiple times without undergoing any significant chemical change. They become soft when heated and harden upon cooling.
- **Thermosetting Plastics**: These are plastics that, once molded and set, cannot be remelted or reshaped. They undergo a chemical change when heated, which makes them hard and rigid.

2. **Bending Properties**:
- **Thermoplastics**: They can be easily bent and deformed without breaking. This flexibility allows them to be used in various applications where shape changes are necessary.
