Kelvin is an absolute temp scale, it equals °C + 273.15. So even a 20°C cup of coffee (68°F, colder than ambient…) is 293 kelvin. IQ only goes up to 200 so that coffee is smarter than Einstein…
Also: Einstein’s IQ was estimated to be around 160 or 170 (he never took the test). 160 kelvin is -113°C… (-171°F… very very cold coffee).
