Enthalpy
Enthalpy is a fundamental concept in thermodynamics, one of the most important branches of physics that deals with the relationships between heat, work, and energy in physical systems. It is a state function that helps…

Entropy
Entropy stands as a cornerstone of physics, encapsulating the measure of randomness or disorder within any physical system and governing the natural direction of physical processes. At its essence, entropy reflects how energy disperses or…

Evanescent Wave
An evanescent wave is a fascinating and subtle phenomenon in physics that arises when a wave encounters a boundary or an interface in such a way that it cannot propagate through the second medium in…

Electric Field
The concept of the Electric Field is one of the most fundamental and powerful ideas in physics, particularly in the study of electromagnetism. The Electric Field describes the influence that an electric charge exerts on…
