Industrial gases are just like the air we breathe, but they are made in special factories and used in different industries to help make things that we use every day.
Think of it this way: you know how we need air to breathe and survive, right? Well, industries need gases like oxygen, helium, nitrogen, and carbon dioxide to do their job too!
For example, factories use oxygen to make steel, glass, and even medicine! Helium helps fill up balloons, but it's also used in things like MRI machines at the hospital. Nitrogen can be used to preserve food, or even to make fireworks! And carbon dioxide is used to make fizzy drinks, but also in things like fire extinguishers.
Overall, industrial gases are just like the regular air we breathe, but they are used in special ways to help make the things we use every day.
