absolute zero
The Kelvin temperature scale has zero as its lowest temperature point, which is known as absolute zero. At this point, particles have minimal motion.
The Kelvin temperature scale has its zero point at absolute zero, which is the lowest theoretically possible temperature where all molecular motion ceases.
-459.67 F Which is absolute zero and that is the temperature at which all molecular activity stops.
A temperature scale with no negative numbers is called the Kelvin scale. On the Kelvin scale, zero is the absolute zero point, which is the theoretically lowest temperature achievable.
The triple point of water (where you can boil water yet not melt ice; this can only happen with the correct temperature and pressure)
Absolute zero is the lowest possible temperature where particles have minimal kinetic energy. At this point, all molecular motion stops completely, making it impossible for any further heat energy to be extracted from a system. It serves as a reference point for temperature measurements on the Kelvin scale.
Yes, it is always positive. 0 K is the lowest temperature there can be.
* kelvin * Celsius both temperature scale have the same gradations but differ in end-point of reference.
The Kelvin scale (apex)
The lowest possible temperature on the Celsius scale is -273.15 °C. This is the same as 0 K on the Kelvin scale, which is the SI base unit of thermodynamic temperature. This temperature is called absolute zero, because it is the point where all molecular motion stops.
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.
Because this zero point is considered the lowest possible temperature of anything in the universe. Therefore, the Kelvin scale is also known as the "absolute temperature scale". The Kelvin scale is a thermodynamic temperature scale where absolute zero, the theoretical absence of all thermal energy, is zero (0 K). Also: That's just the way some things are, really. You don't ask, "Why only 100 degrees Celsius and not 110?"
