What is gas used for for kids?
Natural gas is burned to produce electricity, to cook and to heat buildings. It is also used as fuel for natural gas vehicles for transport. When natural gas is burned in a power station it boils water into steam that spins a steam turbine that turns a generator to make electricity.
What is gas facts for kids?
Gas Facts for Kids
- Like solids and liquids, gas is a common state of matter.
- Pure gases are made up of just one atom.
- Elemental gases are made up of two or more of the same atoms joined together.
- Compound gases contain a combination of different atoms.
- The air we breathe here on Earth is made up of different gases.
What is a gas example for kids?
There are many examples of gases in everyday life, like helium in balloons, the air we breathe, steam from a boiling pot of water, and carbon dioxide bubbles in your soda.
What is gas give example?
Examples of gases include air, water vapor, and helium. A gas is a state of matter that has no fixed volume or shape. In other words, a gas takes the shape and volume of its container. A gas may be either a pure substance (e.g., oxygen, helium, carbon dioxide) or a mixture (e.g., air, natural gas).
How do we get natural gas Kids?
What happens is that ancient plants and animals decompose and form layers over the ground. As the years pass, dirt, rocks, sand and silt bury the organic matter. A combination of pressure and heat then transform the fossils into natural gas.

- Carbon Monoxide.
- Water Vapour.
- Helium.
- Neon.
What is a fun fact about gas?
The word gas was coined in 1650–60 by J. B. van Helmont (1577–1644), a Flemish chemist. It comes from the Greek word for chaos. Hydrogen is the lightest, most abundant and explosive gas on Earth. The atomic weight of Radon is 222 atomic mass units making it the heaviest known gas.
What is gas and example?
Substances that exist in the gaseous phase are commonly referred to as gases. The most common example of a gas is air (the air we breathe is a gas). It can also be considered as a mixture of many gases such as nitrogen, oxygen and carbon dioxide.
What is gas pressure kids definition?
Main page: Pressure. Pressure is the measure of how much pushing force something is putting on another object. In a gas, this is usually the gas pushing on the container of the object or, if the gas is heavy, something inside the gas. Pressure is measured in pascals.
What are some interesting facts about gases?
1. Gas is a state of matter like liquid and solid. 2. Gases that are pure consists of only one atom , neon is an example of a pure gas. 3. Elemental gases consists of 2 or more atoms of the same type for example, Hydrogen gas is made up of two hydrogen atoms. 4. Compound gases unlike elemental gases are made up of a combination of atoms.
What are gases for kids?
Excess abdominal gas in children, also called flatulence, is very common and is typically easy to cure. Gas is primarily made of odorless vapors, including carbon dioxide, nitrogen, oxygen, hydrogen and sometimes methane.
What are some examples of gases?
Particles in gases are widely separated, compared to those in liquids and solids. Examples of gases include: Air. Natural gas. Hydrogen. Carbon dioxide. Water vapor. Freon.
What is an example of gas in science?
A gas does not have a defined shape or volume, so it can expand to fill any size or shape of container. Particles in gases are widely separated, compared to those in liquids and solids. Examples of gases include: Air. Natural gas. Hydrogen. Carbon dioxide. Water vapor.
