Gas is a state of matter that has no fixed shape or volume. Gases can expand to fill any container they are in.
Some examples of gases include air, oxygen, nitrogen, and carbon dioxide. Gases are made up of tiny particles called molecules. These molecules are very far apart from each other, so gases have very low densities.
Gases can be compressed, which means that they can be squeezed into a smaller space. However, when the pressure is released, the gas will expand back to its original size.
Gases are important in many different ways. They are used in cars, aeroplanes, and other vehicles. They are also used in factories to produce many different products.
The stove used gas as its fuel.
Noun: gas, gases.
Adjective: gaseous.

The word "gas" comes from the Greek word gázein, which means "to emit, to exhale". The Greek word gázein is related to the Latin word gas, which also means "to emit".
