Gases are everywhere around us we breath in gas called oxygen but it’s odourless gas. So can you name any gas that has odour? That’s correct the gases that come out of perfume smell really good. Here are five great gases facts for kids.
Gases can take any shape because their molecules aren’t linked together. This means that gases can move freely around any space and can be condensed into any container. Gas molecules can spread out and are very energetic. Most gases are invisible.
The formula for Tungsten Hexafluoride is W6. It is a toxic and colourless gas, with a density of about 13 grams per litre, meaning it is roughly 11 times heavier than air. Tungsten Hexafluoride is a highly corrosive gas, this means that W6 will damage any other substances that it comes into contact with.
Although there are many different types of gases, the two main categories are natural gases and artificial gases. Natural gases are made by nature and they are odourless. They are also lighter than air. Examples of natural gases would be oxygen (O) and nitrogen (N). These two natural gases are the most abundant gases in the atmosphere. Artificial gases are made by humans from chemical reactions. These gases can be very harmful and are often known as man-made greenhouse gases because they have a negative impact on the environment. Carbon dioxide (CO2) and methane (CH4) are known as artificial gases.
Gases are much faster than you may think. Although we can’t always see gases, they are constantly moving around at great speeds. Some gases can move around at up to and over 1,500 kilometre per hour. That is very fast, even faster than an airplane. Some gas particles move so fast they even travel faster than the speed of sound! It is hard to even imagine such speed.
Gas is essential to life on Earth as humans can’t live without oxygen. Plants use carbon dioxide during photosynthesis, if plants couldn’t photosynthesize there would be little food left on the planet and we wouldn’t be able to survive. We use gas in our everyday lives. Gas can be used for cooking, electricity and heating. Gas is very valuable in hospitals. Oxygen and nitrogen is often used to help people who have trouble breathing on their own. When in pain, patients are given gas and air to relieve pain, this gas is called Entonox, which is a mixture of oxygen and nitrous oxide.
We hope you enjoyed learning more things about gases as much as we loved teaching you about them. Now that you know how majestic the universe is, you can move on to learn about other STEM articles like: Chemical Reactions, Acids and Bases, Electromagnetic Waves and States of Matter.
