Properties of a system in thermodynamics

What are the properties of a system?


The properties of the system in thermodynamics are things such as mass, temperature, volume, and pressure. Properties are used to determine the current state of a substance. All the quantities which identify the state of a system are called properties of a system. The thermodynamic properties are divided into two types which are following.

Types of thermodynamic properties:


  • Extensive properties

Extensive properties are called the properties whose value for the whole system is equal to the sum of their values for the individual parts of the system.

 Example: Total volume, Total mass, Total energy of a system

  • Intensive properties

The properties whose value for the entire system is not equal to the sum of their values for the individual parts of the system are called intensive properties. 

 Example: Temperature, Pressure, Density

Difference between characteristic and universal gas constant

-
Some important point on the difference between characteristics gas constant and universal gas constant are explained below. Let us check out one by one below. You can also check out characteristics equation of gas , and general gas equation to know more about it. Difference between characteristics gas constant and universal gas constant: Constant gas characteristics vary from gas to gas but the constant of universal gas is fixed. If you working at human scales, then use universal gas constant, whereas if you want to gas constant that defined per unit mass of a specific gas, then use the specific gas constant.  The characteristic gas constant in equation P = RT is the value of R for a given gas for use. It is equal to the constant of universal gas divided by the molar mass of the particular gas. Characteristics gas Constant applicable for an ideal gas, whereas universal gas constant applicable for a real gas.  Units: Characteristics gas constant - k J / kg K and Univers

Varignon's principle of moments | Varignon's Theorem

Varignon's theorem also called the principle of moments.  Varignon's Principle: Varignon's principle states that if a number of concurrent forces acting on a particle are in equilibrium, then the algebraic sum the moments that each force creates about a single point will be equal to the moment of their resultant force about the same point.   Varignon's Theorem From the above figure, F1 and F2 are two concurrent forces and their resultant is R. The moment produced by R with respect to a moment center O is R × d. The moment produced by the force F1 and F2 is respectively F1 × d1 and F2 × d2.  As per varignon's therorem R d = F1 d1 + F2 d2 Notes: This theorem initially stated for two concurrent forces, but, it is true for any system of forces and any number of concurrent or coplanar forces.  One of the practical applications of this theorem is to find the unknown reactions when a system is known to be in equilibrium under the acti

Difference between moment and couple

-
Moment and couple are two important concepts found in mechanics. They both terms describe the effect and cause of rotation in the system of forces , particle systems, and rigid bodies too.  What is a moment of a force? The turning effect produced by a force applied to a rotational system or on the body at a distance from the axis of rotation is called the moment of force . The moment of a force is the product of the force and the perpendicular distance of the point, about which the moment is required and the line of action of the force. What is a couple OR moment of a couple?   In mechanics, a couple refers to two equal and opposite forces, whose line of action is different from a couple . The couple also called a force couple or pure moment.  Points of difference between moment and couple are discussed below. So let us check out some key differences between them to know more about it.  Difference between moment and couple: The moment is the
