5. Wien’s law explains that objects of different temperatures emit spectra that peak at different wavelengths. Hotter objects emit shorter wavelengths, thus appearing bluer, whilst colder objects emit longer wavelengths, appearing redder. A star’s surface temperature can be deciphered using this method by seeing its …

Pollution is the beginning of a waste into the ambiance doing it impossible to do life on Earth possible to prolong. Pollution is the debut of a contamination into the environment. It is created largely by human actions, but can besides be a consequence of …
Since its discovery 150 years ago, petroleum oil has become lifeline of the world. The entire structure of the modern mechanized world, consisting from transportation system, automobiles, airplanes, railways, ships to space rockets today operates primarily on the energy derived from the fossil fuels/petroleum oils. …
Climate alteration is straight associated with increased atmospheric concentration of gases, and particularly of CO2 produced chiefly by fossil fuel burning. Therefore, accomplishing important decrease of CO2 emanations is pressing. Many different schemes need to be applied for this intent including the increased usage of …
Global Warming: Causes and Effects The term “global warming” is often used synonymously with the term climate change, but the two terms have distinct meanings. Global Warming is a gradual increase in the earth’s temperature. Novdia explained that “global warming refers to the documented historical …
The protein fraction from 70 percent saturation of recrystallised ammonium sulphate was found to have the maximum protein content (19.6 mg/g flower) and hence it was selected for further studies and is abbreviated as PAF in the present study. Characterization of the selected PAF by …
1 Mixtures and Solutions: Candy Chromotography Background Information and Research Biochemists often use this method of separation when studying amino acids or other chemicals from living things. Also they use it to separate a solution with multiple components with different polarites. People use chromoography to …

Mortar is a mixture of sand, a binder such as cement, and water. This mixture is used in masonry construction to fill the gaps between the bricks and blocks used in construction. It is applied as a paste during construction, and then later sets hard, …
The discoveries at Lake Mungo are potentially the most important discoveries made in Australia, if not the world. The skeletal remains uncovered a world that we know very little about. They gave us an insight to the burial practices of the earliest people for both …
Rapid prototyping 3D printers 3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability …

Introduction Histone Proteins are favourably the alkaline proteins which are present in the nucleus of the eukaryotic cell. They are the basic parts responsible for wrapping and organizing DNA into chromosomes in the nucleus. They are the principal protein elements of the chromatin and acts …
Chemotherapy simply means the use of chemicals to treat disease by destroying microorganism or cancerous or tumor cells. Generally, chemotherapy acts by destroying rapidly dividing cells although the mechanism that leads to this differs. Several divisions of chemotherapy agents exist such as the anti-metabolites, plant …

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.
