Werner’s theory of coordination compounds, proposed by Swiss chemist Alfred Werner in 1893, for understanding of complex compounds and laid the foundation for modern coordination chemistry. Werner’s theory explained the existence of coordination complexes, particularly their geometry, bonding, and coordination numbers, offering a coherent explanation for phenomena that had puzzled chemists for years. This theory … Read more

Graham’s law of diffusion explains the connection between the molar masses of gases and the rates at which they diffuse. Thomas Graham, a Scottish chemist, created it in 1833. The process of gas molecules spreading out in response to a gradient in concentration from areas of greater concentration to areas of lower concentration is known … Read more

It is very normal phenomena, when we take a turn while driving a vehicles, cycling, or even walking, we  felt like we are pushed outward. That feeling is due to the effect of centrifugal force, and it becomes even stronger when moving at higher speed or on sharper turn. To counter this force and keep … Read more

Molecular Orbital Theory is a concept in chemical bonding, and explain the behavior of electrons in molecules more effectively than earlier theories like the Valence Bond Theory. Molecular Orbital Theory describes the formation of molecular orbitals by the linear combination of atomic orbitals. These molecular orbitals extend over the entire molecule, and electrons in these … Read more

Friction is the resistive force that occurs when two surfaces in contact move or attempt to move relative to each other. It acts in the opposite direction of the applied force or motion and prevents or resists movement. Friction can occur in various forms, such as static friction (which prevents motion), kinetic friction (which resists … Read more

Equilibrium is reached for a rigid body when it is either at rest or traveling at a constant speed without rotating or changing its direction of motion. When a rigid body is in equilibrium, it doesn’t spin or accelerate in any direction in response to outside torques or forces. Types of Equilibrium of a Rigid … Read more

We frequently conceive, the objects moving in straight lines when we think about motion. Rotational motion is an essential part of everything we do on a daily basis, from the Earth revolving on its axis to a car tire turning. Torque and angular momentum are two basic ideas that aid in our knowledge and description … Read more

An English scientist John Dalton‘s developed a Law of Partial Pressures in 1801. It is a fundamental idea in the behavior of gases, particularly in the circumstance of gas mixtures. Relationship between the aggregate pressure of a mixture of non-reactive gases and the pressures of the constituent gases in the mixture is clarified by Dalton’s … Read more

An object’s movement in relation to another object is the idea of relative motion.  Fundamental to physics in order to understand how objects move in relation to various frames of reference. The analysis has to use vector values for location, velocity, and acceleration when the motion is two-dimensional. Key Concepts of Relative Motion in Two … Read more

First Law of Thermodynamics provides important insight into the behavior of energy in the universe. Often known as the law of energy conservation, it basically asserts that energy can only be changed from one form to another; it cannot neither be created nor be destroyed. This law plays a vital role in the of how … Read more
