Question

Which of the following is an extensive property ?

• A. Heat capacity
• B. Density
• C. Surface tension
• D. Specific heat

Answer 1

The correct option is A Heat capacity

A property of a system, whose magnitude depends upon the amount of matter, is known as extensive property. Properties like mass, volume, internal energy, heat content, free energy, enthalpy, entropy, heat capacity, surface area, energy, etc. are dependent upon the mass of the system and are called extensive properties.

Intensive property: A property of a system, whose magnitude does not depend upon the amount of matter, is known as intensive property. Properties like temperature, pressure, surface tension, viscosity, specific heat, molar energy, molar entropy, density, refractive index, etc., are independent of the mass of the system and are called intensive properties.
