Thermodynamics: Introduction
It is the study of the flow of energy. It encompasses the study of the flow of heat as well as mass.

Liquid State
Characteristics of Liquid State
In liquid, intermolecular forces are strong in comparison to gas.
They have definite volume...
Kinetic Theory of Gases
Kinetic Theory of Gases
Assumptions or postulates of the kinetic-molecular theory of gases are given below. These postulates are related to atoms and molecules which...
Ideal Gas and Dalton’s law of Partial Pressures
A gas that follows Boyle’s law, Charle’s law, Avogadro law strictly, is called an ideal gas. Real gases follow these laws only under certain...
The Gaseous State
Physical Properties of Gaseous State
Gases have no definite volume and they do not have specific shape.
Gases...
Intermolecular Forces
The forces of attraction existing among the molecules of a substance (gaseous, liquid or solid) are called intermolecular forces.
Greater the intermolecular forces, higher is...
Deviation from Ideal Gas Behavior
Real Gas
A gas which does not follow ideal gas behavior under all conditions of temperature and pressure is called real gas.
Deviation with respect to...
States of Matter- Gases and Liquids
Any substance that has mass and occupies space is called Matter. The matter is composed of atoms or molecules. The force of interaction between...
Hydrogen Bonding
Hydrogen Bonding
Hydrogen bond can be defined as the attractive force which binds hydrogen atom of one molecule with the electronegative atom (F, O or...
Bonding in Some Homonuclear (Diatomic) Molecules
Hydrogen molecule (H2)
It is formed by the combination of two hydrogen atoms. Each hydrogen atom has one electron in 1s orbital, so, the electronic...
