Question: What are intensive and extensive properties?
Intensive and extensive properties are two types of physical properties used in thermodynamics and other areas of science to describe the characteristics of matter.
Intensive properties are properties that do not depend on the amount of the substance present. In other words, they are independent of the size or quantity of the sample. Examples of intensive properties include temperature, density, pressure, and specific heat capacity.
Extensive properties, on the other hand, are properties that depend on the amount of the substance present. In other words, they are proportional to the size or quantity of the sample. Examples of extensive properties include mass, volume, length, and total energy.
To illustrate the difference between intensive and extensive properties, consider a sample of water. The temperature of the water is an intensive property because it does not depend on the amount of water present. Whether you have a small cup or a large swimming pool full of water, the temperature will remain the same as long as the water is in thermal equilibrium. However, the total mass of the water is an extensive property because it is proportional to the amount of water present. If you have a larger quantity of water, the total mass will be greater than if you have a smaller quantity of water.
It is important to note that some properties can be either intensive or extensive depending on the context. For example, the density of a substance can be either intensive or extensive depending on whether the total mass or the mass per unit volume is being considered.
