What Is A Matter Of Gas

It doesn t matter how big the container is.

What is a matter of gas.

Unlike solids and liquids gases will occupy the entire container that encloses them. An example is liquid water. 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. 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 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. A gas has neither a defined shape nor volume. Carbon dioxide a gas mixture such as air contains a variety of pure gases. Gas one of the three fundamental states of matter with distinctly different properties from the liquid and solid states.

Why makes the three states of matter different. The molcules of solids are placed very close together and cannot move. The way their particles or molecules are placed. Gas is a state of matter that has no fixed shape and no fixed volume.

A common example is ice. They are easy to push through and may not be visible to human eyes. What is another physical characteristic of gases. The molecules spread out to fill the whole space equally.

Nitrogen dioxide and chlorine gas but these are rarely encountered by students. A noble gas like neon elemental molecules made from one type of atom e g. The three main states of matter are solid liquid and gas. Matter that can change both shape and volume is called a gas.

The molecules of gas are completly free and move around very fast away from other molecules. 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. Gases such as air are the lightest state of matter. The molecules in gases are really spread out full of energy and constantly moving around in random ways.

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. Several exotic states also exist. A liquid has a defined volume but can change state. A solid has a defined shape and volume.

The particles in a gas are not connected to each other so they can float around freely. All gases have weight. Think about a balloon. Oxygen or compound molecules made from a variety of atoms e g.

Solids such as wood and stone have a fixed shape that is difficult to change. Gases can fill a container of any size or shape. Plasma is the fourth state of matter. Some gases are visible e g.

The molecules of liquid are more free and move around. The remarkable feature of gases is that they appear to have no structure at all.
