In thermodynamics, intensive quantities do not depend on the size of the system. For example temperature and density are size-independent, intensive quantities.
Extensive quantities, on the other hand, are proportional to the size of the system: volume is an obvious one, internal energy and entropy are others.
A quick mental test is this: if I were to double the system's size by joining it to a duplicate of itself, would the relevant quantity remain the same or double? If it stays the same it is intensive, otherwise it is extensive.
Intensive properties do not depend on the matter's amount of the physical system (mass density, temperature ...). Extensive properties do depend on the amount of matter that is present (volume, mass and size).
an intensive property is the one that is independent from the mass of number of particles in a system while an extensive proeprty depends on them. Energy (e.g. heat) is a property that depend on the mass or the number of particles in a system. In other words, energy is an extensive property.
Length is an extensive property because it is directly proportional to the amount of material present. The longer the material, the greater its length. It depends on the amount of substance being measured.
Work is an extensive property because it depends on the quantity of substance present. Work is not an intrinsic property of a substance, but rather a measure of energy transfer between a system and its surroundings.
Evaporation is an intensive physical property because it depends only on the type of substance and is not affected by the amount of the substance present.
The different between intensive properties and extensive properties is that one is depend on the amount of matter present and one is do not depend on the amount of matter of present.
Intensive properties do not depend on the matter's amount of the physical system (mass density, temperature ...). Extensive properties do depend on the amount of matter that is present (volume, mass and size).
Intensive agriculture: great production to hectare, efficience, use of fertilizers and pesticides, irrigation, mechanization, application of agricultural sciences, etc. Extensive agriculture: low production to hectare, inefficience, primitive work, etc.
