Heat and Cold


What is the lowest temperature possible?

According to physics, the lowest temperature possible is zero degrees Kelvin (-459.67°F or –273.15°C), which is also known as absolute zero. This is the temperature at which molecular activity stops and it is not possible for any more heat energy to be lost. Such an extreme, of course, does not exist naturally on Earth, except in some university laboratories. The lowest air temperatures can go on the planet is about –130°F (-90°C); an unverified reading of –132°F (-91°C) was reported at Vostok, Antarctica, in 1997.
