In chemistry, what is an object What is a substance What is the difference between an object and a s

An object is a tangible thing. For example, wooden blocks, water glasses, etc.

There is no fixed form of matter, for example, gas can be said to be a substance, liquid can also be used, and solid can also be said to be a substance.

In chemistry, there are many substances that are said. For example, the generation of new matter, and so on.

The difference and connection between matter and object: An object is something very specific that can be seen, touched, and easily felt. For example:

Wooden blocks, air, and water are also real things, but they don't have a real shape, so they are not called objects. Matter is an objective reality that is not affected by human will, such as: water, air, magnetic field, electric field, etc.

Wooden blocks are not called substances because they are too specific, but the components of wooden blocks are called substances. A machine is not called a substance, but the iron used to build a machine is called a substance.

Matter is the physical objects and fields that make up all objects in the universe. For example, air and water, food and cotton, coal and oil, steel and copper, aluminum, and various synthetic fibers, plastics, etc., are all substances. In the world, all the existence around us is matter.

The human body itself is also a substance. In addition to these physical objects, light, electromagnetic fields, etc., are also substances, and they are substances that appear in the form of fields.

There are many types and forms of matter, and the properties of matter are varied. Substances in the gaseous state, substances in the liquid state, or substances in the solid state; elemental substances, compounds, or mixtures; metals and non-metals; minerals and alloys; inorganic and organic; naturally occurring substances and synthetic substances; Inanimate matter and living matter as well as solid matter and field matter, etc. Although there are many types of matter, they have their own characteristics, that is, they can be observed or predicted by theories, and they all have mass and energy.

Having different chemical formulas is different substances, and having the same chemical formula but having different structures is also different substances.

Objects refer to all tangible substances that objectively exist in nature, and are generally divided into gaseous, liquid and solid states. Individuals that are made of matter and occupy a certain space are called objects. The objective reality of its existence can be felt through the human sensory organs.

Something that occupies a certain space and is made of matter. An object is a substance that has a macroscopic shape, macroscopic volume, or macroscopic mass.

Looking around the world we live in, there are all kinds of things, such as: buildings, tables and chairs, cars, ships, ......All these things are called objects.

Objects are made up of air, water, metal, wood, ......and other materials, these materials are called substances. Therefore, we usually say that a physical object composed of matter is called an object. For example: a table is an object, and a table is made of wood, and wood is called a substance.

It is usually a different title for different occasions in which words are used.

For example, in the physical description, if you say that an object moves from A to B, you can't say that the substance moves from A to B, right? In the same way, if we say that matter is composed of molecules, atoms, atomic nuclei and other particles, we can't always say that objects are composed of molecules, atoms, and atomic nuclei, right? Biologists first objected to the fact that living organisms are made up of cells and nuclei.

Conceptually speaking, an object refers to a tangible substance, which can be an elephant or whale that can be observed visually, but also includes invisible molecules, atoms, neutrons and other particles. For example, air is mainly composed of oxygen and nitrogen atoms, and from the perspective of an object, only transparent, colorless, and invisible remain. Of course, you can also say that air is mainly an object composed of oxygen and nitrogen atoms (there is no such thing as "gas"), but it is more rigorously called matter.

It can be seen that they are usually just different names adopted by different literal expressions.

These two objects and substances are not the same concept, an object refers to the shape and size of a thing, etc., and a substance refers to its inner layer and content. So the difference is huge.

Objects refer to very specific things that can be seen and touched, and are easy to feel, such as wooden blocks, air and water are also real things, but they do not have real shapes, so they are not called objects, matter is objective reality, not affected by human will, such as water, air, magnetic field, electric field, etc., wooden blocks are not called material annihilation, because they are too specific, but the composition of wooden blocks is called matter.

Matter has a wider range than what an object represents. An object is something that is perceived through the human sensory organs as an objective reality, usually with a concrete shape or form. However, matter does not necessarily have a specific shape or form, for example, electrons have wave-particle duality, and in general, it is difficult for microscopic particles to determine their specific shape and morphology.

There are six common states of matter: solid, liquid, gaseous, plasma, ultra-solid, and neutron. However, advances in experimental techniques have produced many new states of matter, such as Bose-Einstein condensation and code-trapped fermion condensate.

The study of elementary particles has also led to new states of matter, such as quark-gluon paste. In the history of the natural sciences, many people have been slow to study the exact properties of matter, the concept that matter is a combination of many discrete components.

Chemical substances, as the name suggests, are substances related to chemistry and can refer to the constituent substances of substances.

1 A certain element, compound, etc., can be understood as a component when referring to a mixture 2 Substances, and these substances are composed of some elemental substances and compounds, with a certain chemical composition.
