States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Introduction
The main types of intermolecular forces are London dispersion forces, dipole-dipole interactions, and hydrogen bonding. London dispersion forces are the weakest of intermolecular forces and are caused by the temporary dipole-dipole interactions between atoms or molecules. Dipole-dipole interactions occur when two molecules have a permanent dipole or electric charge. Hydrogen bonding is a stronger type of attraction that occurs when hydrogen atoms are covalently bonded to a highly electronegative atom, such as oxygen or nitrogen.
The strength of intermolecular forces can be affected by different factors, such as temperature, pressure, and the type of substance. For example, the increasing temperature can reduce the strength of London dispersion forces, while increasing pressure can increase the strength of dipole-dipole interactions.
