Like “does the Pope shit in the woods?” or “that train has sailed?”
Also, what good examples can you think of?
But PERC, the chemical used in “dry cleaning” is NOT a dry liquid, so the existence of dry liquids is also not relevant to their example.
I can’t figure out if the confusion is caused by unfamiliarity with the term dry cleaning, or just a feeble grasp of logic.
PERC
Perchloroethylene (aka tetrachloroethene) is a completely non-polar compound, so, yes, it is a dry liquid.
