Which of the following are extensive properties?
\(Heat capacity \quad (B) Entropy \quad (C) Gibbs Energy \quad (D) Concentration \quad (E) Vapour pressure\)
Show Hint
Extensive properties depend on system size; intensive properties do not.
A, B, C and E
A, B, and D
A, B, and D
A, B, E only
The Correct Option is C
Solution and Explanation
Extensive and Intensive Properties
Extensive properties depend on the amount of substance or the size of the system. Let’s evaluate each option:
- Heat Capacity (A): \( \text{Extensive} \) — it increases with the amount of substance.
- Entropy (B): \( \text{Extensive} \) — it is additive over the components of the system.
- Gibbs Energy (C): \( \text{Extensive} \) — it scales with the size of the system.
- Concentration (D): \( \text{Intensive} \) — it is independent of the quantity of substance.
- Vapour Pressure (E): \( \text{Intensive} \) — it depends only on temperature, not system size.
Conclusion: The extensive properties are: \[ \boxed{A, B, \text{ and } C} \]
