What is the difference between physics and chemistry, and what is the difference and connection betw

Physics is the natural science that studies the structure of matter, the interaction of matter, and the laws of motion. It is an experiment-based natural science, and one of the eternal themes of physics is the search for orders, symmetry, and symmetry-breaking10, conservation laws, or invariance

In the field of physics, the fundamental building blocks of the universe are studied: matter, energy, space, time, and their interactions.

Chemistry is the science that studies the composition, structure, properties, and changes of matter. The world is composed of matter, and chemistry is one of the main methods and means used by human beings to understand and transform the material world.

The word "chemistry" literally means "the science of change". Chemistry, like physics, is the basic science of natural science. Many people call chemistry "central science", which is the science that studies the composition, structure, properties and changes of matter.

The rupture of molecules and the recombination of atoms are the basis of chemical change.

Physics refers to the principle of things, mainly macrocosm. Chemistry is the change and composition of microscopic particles. No new matter is formed during a physical change, whereas a new substance is formed during a chemical change.

Chemistry is a reaction at the atomic level, and physics is a reaction at the molecular level or a larger unit.

Physics is the study of the laws of motion, conductivity, float and sink conditions of objects, etc. Whereas, chemistry is the study of matter and its changes. Specifically, it is the study of the composition of substances, the composition of particles, physical and chemical properties, etc.

Physics: electricity, magnetism, etc. State changes: vaporization, liquefaction, etc.

Chemistry: Experiments... Too much.

The content of the study is different:Chemistry is the study of the composition, properties, structure and change laws of matter at the molecular and atomic levels, so as to create new substances. Physics is the study of the most general laws of the motion of matter and the basic structure of matter.

It is the knowledge of the laws of nature; More broadly, physics explores the analysis of phenomena that occur in nature in order to understand their rules.

Contact:Physics and chemistry are both natural sciences, and both study the most basic principles of the world. The laws described by quantum mechanics act on the particles in the microscopic world, so the behavior of any particle is subject to the constraints of this basic law, then the interaction of matter in the chemical process is the interaction of many particles in the microscopic vision, the appearance of chemical reactions is the macroscopic result of the behavior of many particles, physics is the theoretical cornerstone of chemistry, and chemical reactions cannot escape the constraints of physical laws.

Physics Learning Notes.

The basic knowledge of physics in junior high school is relatively simple, but the difficulty is to apply it flexibly when encountering problems. Students can better grasp the ins and outs of knowledge, and also pay attention to learning the teacher's ideas, methods, and entry points for analyzing and solving problems, and gradually improve their thinking ability.

In addition, it is also one of the important ways to improve the learning effect by attaching importance to the integration of theory with practice, and being able to apply the learned physics knowledge to solve problems. This is because physical knowledge is summarized and summarized from production, life, and scientific experiments. Linking theoretical knowledge with practice can not only improve hands-on ability, but also deepen the impression of what has been learned, deepen understanding, and consolidate memory.

1. Chemistry is the study of the composition, properties, structure and change laws of matter at the molecular and atomic levels, so as to create new substances. Physics is the study of the most subtle laws of the motion of matter and the basic structure of matter. 2. The fundamental difference between physical change and macronuclear chemical change is that no new matter is generated in physical change, while chemical change does.

Physical change refers to the fact that although the state of matter has changed, generally speaking, the composition of the substance itself has not changed. Chemical change refers to the process of the conversion or transfer of atoms or electrons between molecules in contact with each other to form new molecules accompanied by changes in energy, which is essentially the breaking of old bonds and the formation of new bonds.

3. The chemical reaction produces a new substance, and the physical reaction only changes the state of the substance, and does not produce a new substance.
