What Is A Matter Of Gas

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.

What is a matter of gas.

A solid has a defined shape and volume. Gas is a state of matter that has no fixed shape and no fixed volume. Matter that can change both shape and volume is called a gas. The molecules spread out to fill the whole space equally.

They are easy to push through and may not be visible to human eyes. Gases such as air are the lightest state of matter. The way their particles or molecules are placed. Several exotic states also exist.

Some gases are visible e g. Water vapor is an. The three main states of matter are solid liquid and gas. What is another physical characteristic of gases.

Oxygen or compound molecules made from a variety of atoms e g. The molecules in gases are really spread out full of energy and constantly moving around in random ways. The particles in a gas are not connected to each other so they can float around freely. A gas has neither a defined shape nor volume.

A noble gas like neon elemental molecules made from one type of atom e g. Plasma is the fourth state of matter. It doesn t matter how big the container is. In addition to solids and liquids gases are also a physical state in which matter can occur.

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. A common example is ice. The molecules of gas are completly free and move around very fast away from other molecules. Gases can fill a container of any size or shape.

A liquid has a defined volume but can change state. The molcules of solids are placed very close together and cannot move. 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. Carbon dioxide a gas mixture such as air contains a variety of pure gases.

Gases have lower density than other states of matter such as solids and liquids there is a great deal of empty space between. The remarkable feature of gases is that they appear to have no structure at all. Unlike solids and liquids gases will occupy the entire container that encloses them. Why makes the three states of matter different.

Think about a balloon. All gases have weight. 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. An example is liquid water.

Gas one of the three fundamental states of matter with distinctly different properties from the liquid and solid states. 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.
