Sort out the intensive and extensive properties among the following:
Temperature, mass, specific heat, density, enthalpy, entropy, concentration, free energy.

Explanation

To classify the given properties as intensive or extensive, we need to understand the definitions of these terms:

1. **Intensive Properties**: These properties do not depend on the amount of substance present. They remain the same regardless of how much material is present in the system. Examples include temperature, density, and specific heat.

2. **Extensive Properties**: These properties depend on the amount of substance present. They change when the size or extent of the system changes. Examples include mass, enthalpy, entropy, and free energy.

Now, let's classify each property from the given list:
