Introduction Colligative properties In liquid solutions, particles are close together and the solute molecules or ions disrupt intermolecular forces between the solvent molecules, causing changes in those properties of the solvent that depend in intermolecular attraction. For example, the freezing point of a solution is …
Background Information Pollution is the chief job faced by today ‘s universe. The scientific definition of pollution is that it is the debut of contaminations into an environment that causes instability, upset, injury or uncomfortableness to the ecosystem i.e. physical systems or populating beings. Pollution …
Plants are essential to life on earth because they capture light energy and convert it into a form – chemical energy – usable by all organisms. Taking the simple molecules carbon dioxide and water, they convert these into a wide range of energy-rich organic substances …
Introduction All living things requires energy to stay warm (mammals in this case) and to carry out other life process i.e. maintenance, growth, movement, daily activities etc. All of the dietary energy in humans is obtained from the main food sources including carbohydrates, fat and …
Introductions: Zeolites are just like clay minerals because both are composed of aluminosilicates, although they differ in their crystal structure in that clay minerals deform in water showing expansion and contraction while zeolites are stable and rigid in water [8]. Both natural and synthetic zeolites …

Conjugation
The word "conjugation" is derived from a Latin word that means "to link together". In organic chemistry terms, it is used to describe the situation that occurs when π systems (e.g. double bonds) are "linked together". An "isolated" π (pi) system exists only between a single pair of adjacent atoms (e.g. C=C)
Kinetic energy
Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Chemical energy is the type of energy released from the breakdown of chemical bonds and can be harnessed for metabolic processes.
Physics
Chemical physics is concerned with the application of the concepts and theories of physics to the analysis of chemical systems and their physical behaviour. While also at the interface between physics and chemistry, it is distinct from physical chemistry.
