Extensive properties of matter are characteristics that depend on the amount of substance present. These include mass, volume, and total energy.
- Mass, the measure of the quantity of matter, increases with the amount of substance.
- Volume, the amount of space occupied.
- Total energy, such as the enthalpy of a system, also scale with the quantity of substance.
These properties are additive, meaning they can be summed for individual components in a system. Extensive properties are essential in thermodynamics and quantitative analysis, helping characterize and measure the behavior of substances in various contexts.
