Gas is one of the four fundamental states of matter, characterized by low density and high compressibility, where particles are widely spaced and move freely. Common examples of gases include oxygen (O₂), carbon dioxide (CO₂), and nitrogen (N₂), all of which are essential for life and various chemical processes. Other examples include helium (He), used in balloons, and natural gas, primarily composed of methane (CH₄), which is used for heating and cooking. Gases can easily expand to fill their containers and do not have a fixed shape or volume.
Evaporation is the process of turning liquid into a gas. Examples of these are the evaporation of water when it is boiled and the evaporation of alcohol at room temperature.
One example is carbon dioxide in soda.

Water vapor, Helium, Methane, Oxygen, Carbon Dioxide.

gas
Some examples are gasoline, iron ore, coal, natural gas, oil, and natural gas.
Petrol (gas in USA), diesel, methylated spirits, liquid gas, are some examples.
O2 - oxygen gas H2 - Hydrogen gas N2 - Nitrogen gas

- nitrogen in atmosphere- methane in atgon
Ice is a solid. water is a liquid. and oxygen is a gas
dry ice
Solid, liquid and gas.
Examples of gas: oxygen, hydrogen, methane, helium, radon, etc.
Carbon dioxide and Carbon monoxide are only two examplesof a gas.
