Outline of physical science - Wikipedia
Physics: The study of matter and energy and the interactions between them. that deals with the atmosphere and its phenomena, such as weather and climate. Apr 12, Most people are familiar with three states of matter – solids, liquids and The physical characteristics of those atoms and molecules decide its state. molecular motion (therefore everything) stops, this is called absolute zero. Organic chemistry involves the study of the structure, properties, and —the study of the effect of chemical structure on the physical properties of a substance. duality, the uncertainty principle, and their relationship to chemical processes.
Bioinorganic chemistry — the study of the interaction of metal ions with living tissue, mainly through their direct effect on enzyme activity. Geochemistry — the study of the chemical composition and changes in rocks, minerals, and atmosphere of the earth or a celestial body.
What is Matter?
Nuclear chemistry — the study of radioactive substances. Solid-state chemistry — the study of the synthesis, structure, and properties of solid materials.
Examples of areas using analytical chemistry include: Forensic chemistry — the application of chemical principles, techniques, and methods to the investigation of crime.
Environmental chemistry —the study of the chemical and biochemical phenomena that occur in the environment. It relies heavily on analytical chemistry and includes atmospheric, aquatic, and soil chemistry.
Bioanalytical Chemistry — the examination of biological materials such as blood, urine, hair, saliva, and sweat to detect the presence of specific drugs. Physical chemists typically study the rate of a chemical reaction, the interaction of molecules with radiation, and the calculation of structures and properties. Sub-branches of physical chemistry include: Photochemistry — the study of the chemical changes caused by light.
What are the branches of chemistry and their definition? | Socratic
Surface chemistry — the study of chemical reactions at surfaces of substances. It includes topics like adsorption, heterogeneous catalysis, formation of colloids, corrosion, electrode processes, and chromatography.
Chemical kinetics — the study of the rates of chemical reactions, the factors affecting those rates, and the mechanism by which the reactions proceed. Quantum chemistry — the mathematical description of the motion and interaction of subatomic particles.

It incorporates quantization of energy, wave-particle duality, the uncertainty principle, and their relationship to chemical processes. Spectroscopy — the use of the absorption, emission, or scattering of electromagnetic radiation by matter to study the matter or the chemical processes it undergoes. It tries to explain them in chemical terms. Biochemical research includes cancer and stem cell biology, infectious disease, and cell membrane and structural biology.
The answers they come up with often lead to unexpected technological applications. For example, all of the technology we take for granted today, including games consoles, mobile phones, mp3 players, and DVDs, is based on a theoretical understanding of electrons that was developed around the turn of the 20th century. Development of sustainable forms of energy production Treating cancer, through radiotherapy, and diagnosing illness through various types of imaging, all based on physics.
Developing computer games Design and manufacture of sports equipment Understanding and predicting earthquakes …in fact, pretty much every sector you can think of needs people with physics knowledge.
Many apparently complicated things in nature can be understood in terms of relatively simple mathematical relationships. Physicists try to uncover these relationships through observing, creating mathematical models, and testing them by doing experiments. The mathematical equations used in physics often look far more complicated than they really are. Nevertheless, if you are going to study physics, you will need to get to grips with a certain amount of maths.
Physicists are increasingly using advanced computers and programming languages in the solution of scientific problems, particularly for modelling complex processes. If the simulation is not based on correct physics, then it has no chance of predicting what really happens in nature.
Most degree courses in physics now involve at least some computer programming.
