Question

Identify the set with only extensive properties.

• A. Temperature, Pressure, Number of moles
• B. Heat capacity, Enthalpy, Entropy
• C. Pressure, Specific heat, Molar heat capacity
• D. Density, Mole fraction, Viscosity \bigskip

Hint:

\textbf{Extensive properties:} Mass, Volume, Internal Energy, Enthalpy, Entropy, Heat Capacity. \textbf{Intensive properties:} Temperature, Pressure, Density, Viscosity, Specific Heat, Molar Heat Capacity.

Answer 1

The Correct Option is B

Concept: Extensive properties depend on amount of substance. Heat capacity, enthalpy, entropy are extensive.

Step 1: Temperature, pressure, specific heat, molar heat capacity, density, mole fraction, viscosity are intensive. Only option B contains all extensive.

Step 2: Write the final answer. \(\boxed{\text{Heat capacity, Enthalpy and Entropy}}\)
