Difference Between Extensive And Intensive Property

Each system has certain characteristics by which its physical conditions are described. These behaviour/characteristics of the system are called the "Properties Of The System". And the value of these properties of the system describes the state of a physical system. There are two main types of Thermodynamics properties and these are; Extensive Or Intensive Property

In this article, we will learn the difference between extensive and intensive properties of the systems with the help of an example.


Difference Between Extensive And Intensive
☛ Dependency On Size/Mass Of Matters 
Intensive properties of a system are those properties whose value does not depend on the size/mass of matter present in the system. While Extensive properties of a system are those properties whose value depends on the size/mass of matter present in the system. 
☛ Uniformity 
The values of comprehensive/extensive properties are not uniform throughout the system while the values of the intensive properties are uniform throughout the system. 
☛ Used For Samples 
An intensive property is used for the identification of samples whereas extensive properties are used for describing the samples.
☛ Changes
Extensive property change the nature of substances whereas intensive property change the physical behavior of substances.
☛ Examples 
Extensive property examples- Volume, mass, enthalpy, entropy, heat capacity, weight, electrical resistance, internal energy, etc.
While Intensive Property examples- temperature, pressure, viscosity, density, melting point, freezing point, flammability, color (in solution), thermal conductivity, etc.


Let Us Understand It With An Example 
The difference between extensive and intensive properties????
A gas is filled in a vessel whose volume is V and temperature is T. When its size is divided into two parts by the separator then we find that the temperature of both the parts remains the same while their volume is reduced by half of the former. As the temperature remained the same and the volume was reduced to half. So it is clear that volume is an extensive property whereas temperature is an intensive property.

Zeroth Law Of Thermodynamic: The Thermal Equilibrium Law

In thermodynamics, we will see two types of walls. One is the Diathermic wall and the other is the adiabatic wall. Let us now go through them one by one.  • So the first is the Diathermic wall- " A Diathermic wall is a wall that allows the easy exchange of heat between two bodies (or between two systems or between system and surrounding) but does not allow the exchange of mass between them ". This means that it is a good conductor of heat. It is sometimes called as metallic wall because it is made of metal. • While the other is the adiabatic wall- " An Adiabatic wall is that wall which neither allows exchange of heat nor mass between two systems (or between system and surrounding) ". Since there is no exchange of heat and mass between the system and its surroundings, the system remains insulated from its surroundings. ➛ That's why whenever we separate the two systems by an adiabatic wall, then there is no concept of equilibrium between them. But whenever we sep...

Characteristics Of Entropy

Entropy is an intrinsic property of a substance and is not affected by the external position of a system or its motion relative to other systems. It is a measure of the randomness of the system. Thus, the higher the randomness of the system, the higher the entropy of the system and the lower the randomness of the system, the lower the entropy of that system. Entropy   " Entropy is defined as a measure of the system's thermal energy that is incapable of doing work ". It is a state function.  For Example Heat is a form of energy that is incapable of doing work. Therefore, the more heat added to the system (or tranfer from the system), the higher (or the lower) will be its entropy.  The formula for change in entropy is given by the equation;                      ➩ ∆S = ∆Q/T For a reversible process, the change in entropy is given as; The Total Change In Entropy Entropy change is zero at equilibrium condition or whenev...

Reversed Carnot Cycle

We have already discussed the concept of “ Carnot Cycle ”   & “ Its Efficiency ” and we have also seen the concept of “ Carnot Theorem And Its Explanation ” in our previous post. As we have already discussed that the Carnot Cycle is a reversible cycle and every process in the Carnot cycle is a reversible process. Therefore, every process of the Carnot cycle can be reversed. And the cycle can be operated in the opposite direction as well. In this article, we're interested in learning more about the reversed Carnot cycle, also known as the reversed Carnot heat engine cycle. Reversed Carnot Heat Engine It is important to note that if a reversible process is reversed, all related energy types—such as heat energy or work energy—will have the same magnitude but the direction of their interaction with matter will be changed. Let us first look at the Reverse Carnot Heat Engine  cycle here; The reversed Carnot heat engine cycle is depicted in the following figure. According to the...
