The lowest kelvin temp is 0 K. All molecular movement stops.
Absolute zero, which is 0 Kelvin, is the lowest temperature in the Kelvin scale. At this temperature, particles have minimum thermal motion and all atomic and molecular motion ceases.
The idea is to start at absolute zero - the lowest possible temperature. This happens to be -273.16 on the Centigrade (Celsius) scale. The Kelvin scale has no negative temperatures; zero degrees Kelvin is the lowest possible temperature.
The Kelvin scale (apex)
If with "k" you mean "Kelvin", no: the lowest possible temperature is zero Kelvin.
That is the lowest possible temperature.
The Kelvin scaleApex
The lowest temperature is known as absolute zero which is equal to 0K (0 Kelvin) and -273.15 Celsius (-459.67F). Absolute zero has never been recorded but is the theoretical temperature of which no heat can be extracted from a system. It is theoretical because at 0K matter would have no pressure and therefore no volume.
Kelvin is the absolute temperature - a temperature where absolute zero, the lowest temperature possible, is defined as zero. Therefore, in the phrase "absolute Kelvin", the word "absolute" seems redundant.
The lowest possible temperature on the Celsius scale is -273.15 degrees Celsius. The lowest possible temperature on the Kelvin scale is 0 degrees Kelvin. Therefore the only temperature scale on which -460 degrees is possible is the Fahrenheit scale.
The Kelvin temperature scale has zero as its lowest temperature point, which is known as absolute zero. At this point, particles have minimal motion.
0 Kelvin is the lowest temperature possible. At this temprature, atoms and molecules have no thermal energy.
The lowest point on the Kelvin scale is absolute zero, which is 0 Kelvin. At this temperature, all thermal motion ceases and particles have minimal energy. Absolute zero is the theoretical coldest temperature possible in the universe.
