Gas separation

Gas separation is like separating your toys into different boxes depending on their types. When we have a gas mixture, it means we have different kinds of gases together, just like when you have different types of toys mixed up in a pile. To use the toys you want, you need to arrange them separately.

Similarly, to use the gas we want, we need to separate it from other gases present in the mixture. But how do we do it? There are different ways. One of the methods is called "adsorption" which is like using a magnet to only pick up a certain type of toy or separating them by their color.

In adsorption, we use some materials that have a special surface that only binds to certain types of gases. Other gases present in the mixture cannot stick to these materials, so they remain free. This way, we can collect only the gas we want.

Another method is called "distillation", which is like boiling water and collecting its steam by cooling it down to get pure water. Similarly, we can heat up the gas mixture to vaporize it, and then separate it by cooling down the desired gas. Each gas has its own boiling point, so when we cool down the gas mixture, different gases will turn back into liquid at different times. We can collect the liquid that contains the gas we want.

Overall, gas separation is a way of separating different types of gases present in a mixture to extract the specific gas that we need. We use different methods to achieve the separation, just like how you separate your toys by color or type.
