What is The Difference Between Physics and Chemistry

Difference between physical chemistry and chemical physics.? Physical chemistry(often abbreviated in the literature – physical chemistry) – a section of chemistry, the science of the structure, structure and general laws of transformation of chemicals.Time explores chemical phenomena using theoretical and experimental methods.

Physical chemistry originated in the middle of the 18th century.  The term “physical chemistry”, in the modern understanding of the methodology of science and questions of the theory of knowledge, refers to M.  v.  Lomonosov, who in 1752 first taught a course of real physical chemistry to students of St. Petersburg University.  In the preface to these lectures, he gives the following definition: 

Physical chemistry is a science which, on the basis of the provisions and experiments of the physical, must explain the reason for what happens through chemical operations in complex bodies.”  In the works of his annular-kinetic theory of heat the scientist deals with issues that fully meet the above problems and methods.  Experimental activities that serve to confirm individual hypotheses and the provisions of this concept are also of this nature.  

MV Lomonosov followed these principles in many areas of his research: in the development and practical implementation of the “science of glass” established by him, in various experiments devoted to the confirmation of the law of conservation of matter and force (momentum);  – In the works and experiments related to the theory of solutions – he developed a comprehensive program of research on this physico-chemical phenomenon, which is in the process of development to this day.

This was followed by a pause of more than a century, and DI Mendeleev was one of the first physico-chemical studies in Russia in the late 1850s.

The next course in physical chemistry was held in 1865 at Kharkov University by N.N.  Beketov had already been read.

The first department of physical chemistry in Russia was opened in 1914 at the Faculty of Physics and Mathematics of St. Petersburg University;  In the fall, M.S.Vrevsky, D.P.

The first scientific journal created to publish articles on physical chemistry was founded in 1887 by W.  Ostwald and J.  Van’t Hoff did it.

Subject of Study of Physical chemistry :

Physical chemistry is the main theoretical basis of modern chemistry, using theoretical methods from such important branches of physics as quantum mechanics, statistical physics and thermodynamics, non-linear dynamics, field theory, etc.  It includes the theory of the structure of matter, which includes: about the structure of molecules, chemical thermodynamics, chemical dynamics and catalysis.  Electrochemistry, photochemistry, physical chemistry of surface phenomena (including adsorption), radiation chemistry, theory of metal corrosion, physical chemistry of high molecular compounds (see Physics of polymers), etc., also belong to separate classes in physical chemistry.  as revered.  chemistry and is sometimes considered as independent classes of colloidal chemistry, physicochemical analysis, and quantum chemistry.  

Most classes of physical chemistry have fairly clear boundaries in terms of objects and research methods, methodological features, and the equipment used.

Difference Between Physics and Chemistry :

These two are at the junction between chemistry and physics, and sometimes chemical physics is included in the structure of physical chemistry. which is not possible to draw a clear line between these sciences.  However, with reasonable accuracy, this difference can be determined as follows:

Physical chemistry considers the total number of processes occurring simultaneously with the participation of multivalents;

Chemical physics examines isolated particles and the interactions between them, i.e. specific atoms and molecules (thus, there is no room for the concept of “ideal gas”, which is widely used in physical chemistry)

Physics and chemistry are the sciences that directly contribute to technological progress in the 21st century.  In both disciplines the laws of the functioning of the surrounding world are studied, in which the smallest particles change.  All natural phenomena have a chemical or physical basis, this applies to everything: glow, combustion, boiling, melting, contact of something with something.

At school everyone studied the fundamentals of chemistry and physics, biology and natural science, but not everyone connected his life with these sciences, not everyone could now determine the line between them.

In order to understand what are the main differences between physics and chemical science, you must first consider them more closely and get acquainted with the main provisions of these disciplines.

About Physics: Motion and its laws

Physics deals with the direct study of the general characteristics of the surrounding world, the simple and complex forms of the motion of matter, the natural phenomena that underlie all these processes.  Science examines the properties of various physical objects and the manifestation of the interactions between them.  Also under the gun of physicists are general patterns for different types of matter;  These unifying principles are called physical laws.

Physics is in many ways a fundamental discipline, as it most comprehensively considers physical systems at various scales.  He is in close contact with all the natural sciences, the laws of physics determine to the same extent both biological and geological phenomena.  There is a deep connection with mathematics, as all physical theory is formulated in the form of numbers and mathematical expressions.  Broadly speaking, the discipline comprehensively studies all phenomena of the surrounding world and the laws of their course, based on the laws of physics.

Chemistry: What does it all consist of:

Chemistry is mainly concerned with the study of properties and substances along with their various transformations.  Chemical reactions are the result of mixing pure substances and forming new elements.

Science connects with other natural disciplines like biology, AB astronomy.  Chemistry studies the internal structure of different types of substances, aspects of interactions, and changes in the components of matter.  At the same time, chemistry uses its own laws and principles, patterns, scientific hypotheses.

Differences Between Physics and Chemistry :

Related to the natural sciences combines these sciences in many ways, but they have much more differences than common:

The main difference between the two natural sciences is that physics studies the various properties of elementary particles (the microworld, this includes the atomic and nucleon levels) and substances that are in a certain state of aggregation.  On the other hand, chemistry studies the very processes of molecules “combining” from atoms, the ability of a substance to enter into certain reactions with a different kind of substance.

Like biology with astronomy, modern physics accepts a lot of irrational concepts in its methodological toolkit, mainly it focuses on the concepts of the origin of life on Earth, the origin of the universe, the “ideal” and the root cause of “materials”.  Relating to the principles of thought in relation to philosophy.  On the other hand, alchemy, moving away from both ancient alchemy and philosophy in general, remains much closer to the rational foundations of the exact sciences.

In physical phenomena the chemical composition of bodies remains unchanged, as well as their properties.  Chemical phenomena involve the transformation of a substance into another with the appearance of its new properties;  This is the difference between the subjects studied in these subjects.

A wide range of phenomena described by physics. Chemistry is a very specialized subject, Jay focuses on studying the microworld (molecular level) as opposed to physics (macroworld and microworld).

Physics deals with the study of physical objects and their properties, and chemistry deals with the structure of these objects, the smallest particles of which are composed and which interact with each other.
