ELI5: Why is it when you allow water to sit and reach room temperature it feels warm but coffee left to reach room temperature feels ice cold?

your mind expects coffee to be hot so when it's room temperature, it feels much colder because it's colder than you expect it to me. one day, brew coffee in a
mug and let it get to room temperature. also put water in a mug and have someone mix up the mugs and blindly feel them. you won't feel a difference.
