Gas is one of the four fundamental states of matter, the other three states are solid, liquid, and plasma. Gases generally have low density and viscosity compared to the other states of matter. Particles in a gas are widely separated from one another, and because of that, they have weaker intermolecular bonds than liquids or solids. Here are 12 facts about gas that you need to know.
1. Gases Can Be Easily Transported
Gases are highly compressible and large volumes of gas can be compressed into a small cylinder and because of that, they can be easily transported.
2. Ozone Gas Protects Life On Our Earth
Ozone gas present in the ozone layer in the stratosphere protects life on earth from harmful ultraviolet (UV) radiation.
3. Helium Can Change A Person’s Voice
Helium is lighter than air, which means sound moves faster through helium than through air. Thus, when you breathe in helium, your voice travels much more quickly across your vocal cords. Because of that, when helium is inhaled, it will change a person’s voice.
4. Gases Have Higher Entropies
Gases have higher entropies than solids or liquids because the atoms in gases are far apart from each other. Entropy is usually described as the degree of randomness.
5. 75% Of The Mass Of The Universe Is Made Of Hydrogen
Hydrogen is by far the most abundant element in the universe, making up almost 3/4th the mass or 75% of the mass of the universe. It is abundantly found in stars, gaseous planets, and nebulas.
6. Living Things Need Oxygen To Survive
Oxygen is one of the most important gases as most living things need oxygen to survive.
7. Gases Are Good Fuels
Gases are generally considered good fuels as they cause less air pollution and these fuels burn completely and do not leave any residues.
8. Tear Gas Is Used To Disperse The Mob
Tear gas is generally used by the police to disperse the mob or the crowd. It was first used in World War I in chemical warfare.
9. CNG Is The Cheapest And Least Polluting Fuel
Compressed Natural Gas (CNG) is used in transport systems or public transport vehicles like cars, buses, auto rickshaws, and trucks. According to many researchers and transport industry experts, CNG is practically the cheapest and least polluting fuel for commercial transportation.

10. CO2 Levels Are Increasing
Carbon dioxide (CO2) is a greenhouse gas. Due to the cutting of trees, CO2 levels in the atmosphere of our Earth are increasing. Thus, temperatures are also increasing around the world.

11. Collisions Between Gas Molecules Are Perfectly Elastic
One of the amazing scientific facts about gas is that all collisions between gas molecules or particles in a gas are perfectly elastic. None of the energy of a gas particle is lost when it collides with another particle in the gas or with the walls of the container.
12. Helium Is Lighter Than The Air
At parties and carnivals, the helium balloons you get always float in the air because helium is lighter than the air surrounding it.
These are 12 facts about gas that everyone should know.
