Step 1: Understanding the Question:
The question asks to identify an intensive property from the given list.
Step 2: Detailed Explanation:
1. Extensive Property: Depends on the mass or size of the system (e.g., mass, volume, internal energy, enthalpy, entropy).
2. Intensive Property: Independent of the mass or size of the system (e.g., temperature, pressure, density, molar volume).
3. Volume, Enthalpy, and Entropy all double if the system size doubles; they are extensive.
4. Molar volume ($V_m$) is the ratio of two extensive properties (Volume / Number of moles). Such ratios are always intensive. It describes the volume of one mole of substance regardless of how much total substance you have.
Step 4: Final Answer:
Molar volume is an intensive property.
