Principle of Corresponding States (PCS)
The principle of Corresponding States (PCS) was stated by van der Waals and reads: “Substances behave alike at the same reduced states. Substances at same reduced states are at corresponding…
Pure Substances
Phase Change and Property Diagrams In this chapter we consider the property values and relationships of a pure substance (such as water) which can exist in three phases – solid,…
Internal Energy
One of the thermodynamic properties of a system is its internal energy, E, which is the sum of the kinetic and potential energies of the particles that form the system. The internal…
Two property Rule in Thermodynamics
Pure Substance Let we first go through the definition of pure substance to understand its meaning. “A pure substance is defined as one that is homogeneous and invariable in chemical…
What is Thermodynamic Equilibrium?
Thermodynamic Equilibrium Defined Let us suppose that there are two bodies at different temperatures, one hot and one cold. When these two bodies are brought in physical contact with each…
Thermodynamic State
Thermodynamic state A system will be called in a particular thermodynamic state if it satisfies both the below mentioned criteria. 1. All the thermodynamic properties of the system are uniform throughout the system 2. All the…
What is Thermodynamic Property – Definition
Thermodynamic Properties Within thermodynamics, a physical property is any property that is measurable, and whose value describes a state of a physical system. Our goal here will be to introduce thermodynamic…
