The Coldest Cold
Think it’s cold outside? Well, it could be a lot colder.
Theoretically, absolute zero – zero on the Kelvin scale – is the lowest possible temperature. It is the point at which the atoms in a substance are completely at rest, transmitting no thermal energy. Zero on the Kelvin scale is the equivalent of minus 459.67 degrees Fahrenheit or minus 273.15 degrees Centigrade.
