What is the main difference between extensive and intensive physical properties?

Answer 1

The main difference between extensive and intensive physical properties is that extensive properties depend on the amount or size of a substance, while intensive properties do not.

Extensive properties change with the amount or size of the sample. Examples of extensive properties include mass, volume, length, and total energy. For example, if you have two identical samples of a substance, the mass, volume, and energy of the combined samples would be the sum of the individual masses, volumes, and energies.

On the other hand, intensive properties do not depend on the amount or size of the substance. They remain constant regardless of the sample size. Examples of intensive properties include temperature, density, color, boiling point, and melting point. For example, the boiling point of water is 100 degrees Celsius, whether you have a small or large amount of water.
