An intensive property is one that does not depend on the quantity of matter present. Which of the following is an intensive property?
Answer and explanation
Correct answer: A. Electrode potential
- Step 1: Recall the definitions: extensive properties scale linearly with system size/mass; intensive properties are independent of system size.
- Step 2: Volume, internal energy (), and enthalpy () are extensive because doubling the system doubles their values.
- Step 3: Electrode potential () is an intensive property related to free energy by , representing electrical potential difference per unit charge.
Answer
Electrode potential ().
Why not the others: Volume scales directly with mass and volume size (extensive); Internal energy increases proportionally with number of particles (extensive); Enthalpy is an additive thermodynamic quantity (extensive).
