AIIMS 2018 Physics Properties of Systems MCQ Question

Extensive properties, such as volume (V) and energy (E), depend on the amount of substance present in a system; for example, doubling the quantity of H₂O will double its volume and energy. In contrast, temperature (T) and pressure (P) are intensive properties, meaning they remain constant regardless of the amount of substance, as they are characteristic of the material itself. Specific heat capacity (Cₚ) is also an intensive property, as it describes how much heat is required to raise the temperature of a unit mass of a substance, independent of the total mass. Thus, only option A correctly identifies extensive properties.
