Which among the following is NOT an intensive property?

Options

  1. AInternal energy
  2. BViscosity
  3. CSurface tension
  4. DSpecific heat

Correct answer

A. Internal energy

Step-by-step solution

Internal energy is not an intensive property, but rather an extensive property: An intensive property is independent of the amount of a substance in a system. In contrast, an extensive property depends on the amount of a substance in a system. Example: Internal energy is an extensive property because its magnitude depends on the amount of substance in a given state.
