4 Types of Matter

Introduction to 4 types of matter:

Matter is a general term that is used for the substance from which all physical objects are made. Matter includes the atoms and other particles which will have the mass. The common way of defining the matter is that it has mass and occupies certain volume.Matter commonly exists in four states called as solid, liquid, gas and plasma.

Explanation to 4 Types of Matter(solids & Liquids)

Solids: Solid is one of the four common states of matter. solids have definite shapes unlike liquids and gases. The solid keeps its own shape where as if we pour some water into a glass or fill any balloon with gas, the liquid or gas takes the shape of the container which they used.

Liquids: Liquid is one of the four common states of matter. A liquid does not have any fixed shape or size as a solid but the liquid takes the shape of a container that is used. Liquids flow from one place to another. Unlike a gas, a liquid will have a distinct surface called as free surface. By taking an example, water present in a glass has a surface where water ends and the air above it begins.

Explanation to 4 Types of Matter(gases & Plasma)

Gases: Gas is one of the four common states of matter. In Earth's atmosphere the air is mostly a mixture of different types of gases. Usually a gas has much lower density than a solid or liquid. The quantity of gas doesn't have a specific shape just as liquid but different from solid. If a gas is enclosed in a container then it will take the shape of the container same as a liquid. The atoms or molecules in a gas are much farther from each other than in a solid or a liquid.

Plasma: The fourth state of matter is called as plasma. Most of the matter present in this universe is found in the plasma state. All the matter that is present in the universe is made up of atoms. An atom has a nucleus which has a positive charge. All the electrons which are present orbits the nucleus. The electrons which has a negative charge are attracted by the nucleus.
