Which of the following is an intensive property. Surface tension, mass, volume, enthalpy, density

Explanation

To determine which of the given properties is an intensive property, we first need to understand the definitions of intensive and extensive properties.

### Step-by-Step Solution:

1. **Define Intensive and Extensive Properties**:
- **Intensive Properties**: These properties do not depend on the amount of matter or the size of the system. Examples include temperature, pressure, and surface tension.
- **Extensive Properties**: These properties depend on the amount of matter present. Examples include mass, volume, and enthalpy.
