What Is A Matter Of Gas

Gases such as air are the lightest state of matter.

What is a matter of gas.

Gases have lower density than other states of matter such as solids and liquids there is a great deal of empty space between. Gas is a state of matter that has no fixed shape and no fixed volume. The molcules of solids are placed very close together and cannot move. They have neither a definite size nor shape whereas ordinary solids have both a definite size and a definite shape and liquids have a definite size or volume even though they.

Water vapor is an. The molecules of gas are completly free and move around very fast away from other molecules. What is another physical characteristic of gases. Think about a balloon.

In addition to solids and liquids gases are also a physical state in which matter can occur. An example is liquid water. A gas has neither a defined shape nor volume. They are easy to push through and may not be visible to human eyes.

Solids such as wood and stone have a fixed shape that is difficult to change. The remarkable feature of gases is that they appear to have no structure at all. A common example is ice. The molecules spread out to fill the whole space equally.

Nitrogen dioxide and chlorine gas but these are rarely encountered by students. All gases have weight. A gas is a sample of matter that conforms to the shape of a container in which it is held and acquires a uniform density inside the container even in the presence of gravity and regardless of the amount of substance in the container. Oxygen or compound molecules made from a variety of atoms e g.

Plasma is the fourth state of matter. Some introductory chemistry texts name solids liquids and gases as the three states of matter but higher level texts recognize plasma as the fourth state of matter. Gas is one of the four fundamental states of matter the others being solid liquid and plasma a pure gas may be made up of individual atoms e g. The particles in a gas are not connected to each other so they can float around freely.

Why makes the three states of matter different. A noble gas like neon elemental molecules made from one type of atom e g. The way their particles or molecules are placed. The three main states of matter are solid liquid and gas.

The molecules of liquid are more free and move around. If not confined to a container gaseous matter also known as vapor will disperse into space the term gas is also used in reference to the state or condition. Matter that can change both shape and volume is called a gas. A solid has a defined shape and volume.

A liquid has a defined volume but can change state. Gas one of the three fundamental states of matter with distinctly different properties from the liquid and solid states. Some gases are visible e g. It doesn t matter how big the container is.

Carbon dioxide a gas mixture such as air contains a variety of pure gases. Several exotic states also exist.
