Steam, carbon dioxide
The clouds which are water vapor (this is your gas) rain (which is your liquid) down in the form of percipitation.
There are a number of examples of solid in gas solutions, such as smoke, in which carbon and air are in the form of a solution. Automobile exhaust is another example of solid in gas solution. An example of such solution is Iodine vapors in the air.
water in the form of gas is water vapor.
gas
Steam (in all its uses), water vapor (as in humidity).
Water is a common form of liquid that exists naturally on Earth. Other examples of liquids include milk, juice, and oil.
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
Examples of chemical equations include: 2H2 + O2 -> 2H2O (hydrogen and oxygen gas combine to form water) 2Na + 2H2O -> 2NaOH + H2 (sodium reacts with water to form sodium hydroxide and hydrogen gas) Fe + S -> FeS (iron and sulfur combine to form iron sulfide)
