Which is intensive property?
Correct answer: D. All of the above
- A. Boiling point
- B. Molarity
- C. Freezing point
- D. All of the above
Explanation
An intensive property does not change with the size or amount of the sample; it is inherent to the substance itself. The boiling point, freezing point, and molarity are all examples of intensive properties because they are characteristic of the substances and remain constant regardless of the quantity present. In contrast, extensive properties like mass and volume depend on the amount of substance present, thus changing with the size of the sample.

About System, Surroundings and State Functions
A system is the part of the universe under study, while everything outside it is the surroundings; the boundary separates them. State functions such as pressure, temperature, volume, internal energy and enthalpy depend only on the state, unlike heat and work, which depend on the path taken.
