Metallic Conduction

Introduction The outermost electrons of a metal atom are free to move from one atom to another, unlike polymers that are locked in a chain structure. When you apply current to a wire, new electrons are introduced, causing existing free electrons to move to make room for them, as long as the excess electrons on […]

Measurable Properties of Gases: Gas Laws – Boyle’s Law

Introduction Several scientists created gas laws around the end of the 18th century. Each gas rule is identified by the names of the scientists who proposed it. As a result, we now identify the following five key gas laws. Boyle’s Law describes the link between a gas’s pressure and volume. The connection between the volume

Manufacture of Pure Gases

The air available in nature consists of a mixture of pure gases. These gases always contain individual atoms (like noble gases) or atomic gas (as neon), or compound molecules containing a variety of atoms (like carbon dioxide). Each of these gases has its applications. Also, each gas must be separated from the mixture and converted

Magnetic Properties

Magnetism is a natural force that is produced by the movement of electric charges. Some of these motions are microscopic and occur within magnets, which are a type of magnetic material. The magnetic fields created by moving electric charges, or magnets themselves, have the ability to attract or repel other magnets, as well as alter

Macromolecular

Before we begin to explore all the aspects of the various colloids present in surface Chemistry, let us first understand the concept of colloids. What are colloids? Colloids are particles that have a diameter between 1 to 1000 nanometers. It consists of a mixture of particles. These particles are spread throughout the solution in an

Liquid Meniscus in Capillarity

A meniscus is a curve in the surface of a molecular substance (water) when it encounters another material. Imagine water holding to the inside of a glass to get a sense of what it’s like. Adhesion is responsible for a meniscus, and this has to do with the high surface tension of water. The molecules

Law of Partial Pressures

The rule that states that the total pressure exerted by a mixture of gases equals the sum of the partial pressures exerted by each individual gas in the mixture is known as Dalton’s law of partial pressures (or vice versa). The overall pressure exerted by a mixture of two gases A and B, for example,

Law of Partial Pressure

Dalton’s law of partial pressure states that in a mixture of non-reacting gases, the total pressure exerted equals the sum of partial pressure of an individual gas. Therefore, the pressure imposed by a single gas in a mixture of gases is known as its partial pressure. For example, if a container contains a combination of

Kössel’s Theory of Chemical Bonding

It is common knowledge that anything that has mass and can occupy space is called matter. Matter is made up of elements of more than one type. No element except the noble gases can exist independently in nature. They usually occur as a group of atoms. There is some sort of force holding the group
