Hydrofluoroolefin
Hydrofluoroolefin is a big word that means a chemical that is made up of certain atoms, kind of like how words are made up of letters. This chemical is used in things like air conditioners and refrigerators to help keep things cold.
But why use hydrofluoroolefin instead of other chemicals? Well, it turns out that some other chemicals, like ones called CFCs, can actually hurt the environment by making a big hole in the ozone layer.
So scientists found hydrofluoroolefin, which still keeps things cold, but doesn't hurt the ozone layer like those other chemicals do.
Overall, hydrofluoroolefin is a cool chemical that helps keep things cold without hurting our planet.
