Consider the following thermodynamic properties: (A) Volume (B) Temperature (C) Density (D) Enthalpy (E) Pressure Which of the above are intensive properties? Which of the above statements is/are correct?

  1. (A) and (D) only
  2. (B), (C) and (E) only
  3. (B) and (C) only
  4. (A), (D) and (E) only

Correct answer · Option 2

(B), (C) and (E) only

Explanation

Temperature, density, and pressure do not depend on the quantity or size of matter in the system, so they are intensive properties. Volume and enthalpy are extensive properties.
