Think about a balloon.
What is a matter of gas.
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.
The remarkable feature of gases is that they appear to have no structure at all.
The three main states of matter are solid liquid and gas.
In addition to solids and liquids gases are also a physical state in which matter can occur.
A noble gas like neon elemental molecules made from one type of atom e g.
Plasma is the fourth state of matter.
The particles in a gas are not connected to each other so they can float around freely.
The molcules of solids are placed very close together and cannot move.
It doesn t matter how big the container is.
Gases can fill a container of any size or shape.
A solid has a defined shape and volume.
What is another physical characteristic of gases.
Matter that can change both shape and volume is called a gas.
Gases such as air are the lightest state of matter.
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.
The way their particles or molecules are placed.
Nitrogen dioxide and chlorine gas but these are rarely encountered by students.
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 liquid has a defined volume but can change state.
The molecules spread out to fill the whole space equally.
Gas one of the three fundamental states of matter with distinctly different properties from the liquid and solid states.
The molecules in gases are really spread out full of energy and constantly moving around in random ways.
A common example is ice.
Solids such as wood and stone have a fixed shape that is difficult to change.
The molecules of liquid are more free and move around.
Why makes the three states of matter different.
The molecules of gas are completly free and move around very fast away from other molecules.
Carbon dioxide a gas mixture such as air contains a variety of pure gases.
Several exotic states also exist.
Oxygen or compound molecules made from a variety of atoms e g.
Some gases are visible e g.
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.
All gases have weight.
A gas has neither a defined shape nor volume.
Water vapor is an.
An example is liquid water.
Unlike solids and liquids gases will occupy the entire container that encloses them.
Gas is a state of matter that has no fixed shape and no fixed volume.
