ELI5: Explain Like I'm 5

Gas to liquid

When you put something in a pot on the stove, like water, the heat from the burner turns it from liquid to gas, like steam. The same thing happens with gas. When you heat it up, it turns into a liquid. Gas is made up of tiny particles, like atoms or molecules. When they get hot, they move around faster and create steam. But, when they cool down, they slow down and stick together, making a liquid. So when you heat up gas, it turns into a liquid.
