The word physics comes from the Greek term -phisis- which alludes to nature and reality. It is a natural science that studies the properties of nature by analyzing the characteristics of matter, energy and time, as well as the relationships or links that exist between these elements.
Physics is considered a discipline of experimentation that develops theories and statements to explain the phenomena that occur in nature. In addition, it is considered a fundamental or basic science, because it is a science that does not have immediate practical purposes but rather seeks to increase knowledge about certain phenomena.
On the other hand, physics studies the properties of bodies and the laws that govern the transformations that affect their state and their movement, without altering their nature, that is, it is responsible for analyzing transformations or physical phenomena.
Among the different branches of physics we can find astrophysics, atomic physics, biophysics, physical chemistry, condensed matter physics, molecular physics, nuclear physics, particle physics, quantum physics and thermodynamics, among others. others.
For example : the fall of a body or the melting of ice are physical phenomena studied by physical science.
Chemistry is the natural science that studies the composition, structure, transformation and properties of matter. It also studies the changes that occur in matter during so-called chemical reactions. Similarly, chemistry is divided into two well-defined groups, organic chemistry and inorganic chemistry. As many know, organic chemistry deals with the study of chemical reactions and the combination of different carbon atoms, hydrocarbons and their derivatives, encompassing all natural elements and organic (living) tissues. In contrast, inorganic chemistry studies minerals and artificial products obtained from chemical reactions.
In general, chemistry studies the atoms, the different compounds and the transformations that occur between them, as well as the reactions that may arise between the elements involved. Obviously, it is a science of great importance of chemistry for human life, since it is the key to understanding many of the daily processes that occur in our lives.
Biochemistry, analytical chemistry, industrial chemistry, applied chemistry, astrochemistry, neurochemistry, and physical chemistry are some branches of chemistry.
For example: the combustion of paper and the dissolution of salt in water are chemical processes studied by chemical science.
According to the above, the following table is presented where the most important differences between physics and chemistry are indicated:
|It studies the properties and behavior of energy and matter.||It studies both the composition, structure and properties of matter, as well as the changes it undergoes during chemical reactions and its relationship with energy.|
|It studies changes in matter at a superficial and temporal level.||It studies changes in matter at the structural and molecular levels.|
|It is based on the movement and state of these particles without going into details of their evolution.||It is based on the study of particles and their development.|
