What is the main difference between extensive and intensive physical properties?
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.
The main difference between extensive and intensive physical properties lies in how they scale with the amount or size of the sample being measured.
1. Extensive properties: These properties depend on the amount or size of the sample being measured. They change as the sample quantity changes. Examples of extensive properties include mass, volume, and total energy. For instance, if you double the amount of a substance, the mass and volume will also double.
2. Intensive properties: These properties do not depend on the amount or size of the sample being measured. They remain constant regardless of the quantity of the substance. Examples of intensive properties include temperature, density, and specific heat. For example, no matter how much of a substance you have, the temperature or density will remain the same.
In summary, the key distinction is that extensive properties change with the amount of material, while intensive properties do not.
The main difference between extensive and intensive physical properties lies in how they depend on the amount or size of the substance being observed.
1. Extensive properties: These properties depend on the amount or size of the substance being observed. Examples of extensive properties include mass, volume, and total energy. For instance, if you have two identical objects, the one with greater mass or volume will have a greater extensive property value. To determine the extensive property, you need to measure or calculate the total amount of the substance present.
2. Intensive properties: These properties do not depend on the amount or size of the substance being observed. Examples of intensive properties include temperature, density, and color. Regardless of the amount or size of the sample, the intensive property remains the same. For example, whether you have a small or large amount of water, the boiling point will remain at 100 degrees Celsius. To determine the intensive property, you can directly measure or observe it without considering the quantity of the substance.
In summary, the main difference between extensive and intensive physical properties is that extensive properties depend on the amount or size of the substance, while intensive properties do not.
