Which of the following is an extensive property of the system?

Options

A. Refractive index
B. Viscosity
C. Tempertature
D. Volume

Explanation

To determine which of the following is an extensive property of the system, we need to understand the definition of extensive properties. An extensive property is one that depends on the amount or quantity of the substance in the system.

Let's analyze each option provided:

1. **Refractive Index**: The refractive index of a substance is a ratio of the speed of light in a vacuum to the speed of light in the substance. It is independent of the quantity of the substance. Therefore, refractive index is not an extensive property.

2. **Viscosity**: Viscosity is a measure of a fluid's resistance to flow. Similar to refractive index, viscosity does not change with the amount of the substance. For example, the viscosity of 1 ml of a liquid will be the same as that of 100 ml of the same liquid. Thus, viscosity is not an extensive property.
