ELI5: Why does liquid at room temperature taste warm but food at room temperature tastes cold?
gpt
Well, it's a matter of expectations. And it's not a matter of liquid vs solid.

If you drink a room temperature Pepsi, it will seem warm, because you're used to it being served cold. If you have a coffee at room temperature it will seem cold because you're used to it being served hot.

I am sure you've eaten potato chips at room temperature. Did they seem cold to you? Probably not, because you're used to eating them at that temperature. If you are used to eating cheese straight out of the fridge, room temperature cheese will seem quite warm.
