How are we able to drink hot liquids, yet if that very same liquid spilled on our hand, it would hurt like crazy? Is there some kind of “internal AC” in our mouths?

Also, hot liquids are usually sipped and/or slurped. In sipping, only a small amount is ingested at a time, and this mixes with the saliva in your mouth, instantly cooling it. When slurping, air in introduced with the liquid, allowing a degree of instantaneous evaporation.
