What is a large property?
In physics and chemistry, the extensive property of the substance is a property that depends on the amount of this substance in the physical system. On the contrary, intensive properties have no dependence on the amount of material in the system - the intensive properties of the substance will not change no matter how much it exists. The popular examples of the extensive properties of the substance include its mass and volume.
One of the most basic illustrations of differences between extensive properties and intense properties can be found in the ownership of density. The density of the object can be found by dividing the object of the object by its volume. Its weight and volume are said to be extensive properties because it depends on the amount of material in the building - the more material, the greater the weight and volume. Assuming the composition of the object is uniform, however, the density remains the same regardless of the size.
A simple way of remakeing differences between intense properties and extensive features is that when two identical systems are combinedThe STI remains the same while the extensive feature would double. For example, the combination of two identical gas canisters with the same content would double the weight of the system, which is an extensive property. The pressure inside the canisters is intense and remains the same.
in thermodynamics, internal energy, entropy, free energy and gibbs entropy are considered to be extensive properties. Their amount depends on the size of the thermodynamic system. These values must not be confused with specific energy, specific entropy, specific free energy of GIBBS or specific entalpia that are intense.
Generally, a large feature divided by other extensive property will lead to intensive property. The density, expreted from examples, is sitting as a weight ratio to volume. Specific properties in thermodynamics are also intense. For example, a specific thermal capacity of a substance may be expressed by JAKO ratio of the heat capacity of the substance to the mass of the fabric.
Confusion most often exists in terms of differences between extensive properties and intense properties, but there is also confusion between extensive properties and perception of the system. The perception of a particular system describes the observer's thoughts at an abstract concept, such as color or smell. Unlike the abstract concept, a large -scale property can be quantified and measured.
