Chapter 9: Problem 10

Identify the intensive quantities from the following: (a) Enthalpy (b) Temperature (c) Volume (d) Refractive index.

Short Answer

Expert verified
Among enthalpy, temperature, volume, and refractive index, temperature and refractive index are intensive properties, while volume and enthalpy are extensive properties.

Step by step solution

01

Identify the intensive quantity: Enthalpy

Enthalpy is defined as the heat content of a system at constant pressure. Essentially, it's the total energy of a thermodynamic system. As it depends on the amount of substance present, it qualifies as an extensive quantity, not an intensive quantity.
02

Identify the intensive quantity: Temperature

Temperature is an intensive quantity as it does not depend on the amount of substance present. It is a measure of the average kinetic energy of particles in a system and does not change with the quantity of a substance.
03

Identify the intensive quantity: Volume

Volume, like mass, is an extensive property. It changes with the amount of substance present, hence it is not an intensive quantity.
04

Identify the intensive quantity: Refractive Index

The refractive index of a medium is a measure of how much it reduces the speed of light. It is an intensive property because it doesn't change with the amount of substance present. Rather, it depends on the nature of the medium.
