What is physical chemistry?
literally millions of chemical compounds exist. The ways in which these compounds and their components react and interact with each other follow certain physical principles that explain their behavior. Physical chemistry is therefore the basis on which all other areas of chemistry are based, and this science is also relevant to virtually all other scientific areas. Physical chemistry is included in four areas of the object, including thermodynamics, quantum chemistry, chemical kinetics and statistical thermodynamics.
Thermodynamics is the study of energy conversion into heat and work. In this context, work is defined as energy transmitted by force; For example, digging the ball is a form of work in which a person who kicks the ball transmits from his foot to the ball, causing the ball to move. Thermodynamics also studies ways in which the conversion process can be changed by changing variables such as system pressure and temperature. Quantum chemistry
is a theoretical science that describes how molecules connect to each other using a princeCIPs of quantum field and quantum mechanics. These principles describe how atoms and subatomical particles behave in different systems, and again follow how the molecules behave. Theoretically, all chemical systems can be described using quantum chemistry, but in practice only very simple systems can be examined.
Chemical kinetics studies chemical processes. The speed of the chemical process is simply the speed at which the chemical reaction occurs. For example, contrast at the speed of iron oxidation, which is a very slow process, with the speed of fuel combustion, which is the process of splitting a second. Chemical kinetics also study how changing variables such as pressure and temperature, speed at which reactions occur.
These aspects of physical chemistry are connected by the fourth, called statistical thermodynamics. This field applies to energy distribution in chemical systems and also combinesMicroscopic and macroscopic worlds. The main objective of statistical thermodynamics is to interpret macroscopic properties of different types of matter in relation to the interactions between their constitutional microscopic molecules and particles.
by studying these four concepts, modern physical chemistry seeks to understand complex chemical problems in connection with biological, environmental and material sciences. Although they are widely heterogeneous, the principles of physical chemistry are relevant to all, including biological and physical and chemical sciences. In fact, this is a highly multidisciplinary science, precisely because the chemical principles they study are relevant to all biological and chemical systems.
