Me no sciency, but I’m guessing that the difference between room temp and 0 Celsius (frozen) is only like 20-25 degrees, where as boiling temp is 100 degrees (~75 degrees away from room temp).

Also, anything under room temp general feels ‘cold’ where as a few degrees under boiling things start to go from hot to ‘warm’ fast.
