Extensive Properties: Extensive properties are those that depend on the quantity of matter present in a system. These properties change when the amount of substance in the system is altered.
Examples:
- Mass
- Volume
- Energy
- Enthalpy
Intensive Properties: Intensive properties are independent of the amount of substance in the system. These properties remain constant, regardless of the quantity of matter.
Examples:
- Temperature
- Density
- Pressure
- Refractive index
