"Absolute zero" (Zero Kelvin) is a theoretical temperature, at which all atomic motion stops. This temperature can't be reached in practice, but we can get very close. Laboratories on Earth have reached temperatures of less than a microKelvin (millionth of Kelvin, or millionth of a degree from absolute zero). In outer space, it usually doesn't get much colder than about 3 Kelvin, because of a background radiation equivalent to that temperature.

How did Kelvin calculate absolute zero?
This is just the rough answer, as I am looking for more details myself... but Kelvin was trying to discover at what temperature the ideal gases turned to liquid (He, H, etc), and he then used those numbers to plot a line that supposedly gave him the temperature that would mean there was no 'energy' left in a substance, and thus be as cold as it cold possibly be. There are flaws to his theory, but it is called Kelvin because of him. Keep in mind that it is likely that there are temperatures colder than 'absolute zero'... currently they are called 'negative temperatures'. Some people postulate that below a certain temperature that the matter would actually contain *more* energy than at a relative 'absolute zero', and if both of those turn out to be 'facts' then pretty much the whole idea of 'absolute zero' is blown out of the water 'so to speak'. Nova has a great special called Absolute Zero that you can rent from Netflix that tells about the history of 'cold'. I recommend it to anyone interested in this topic.
What is the difference between absolute temperature scale and kelvin scale urgent I am convinced that there is a difference?
The Kelvin scale is an absolute temperature scale where 0K represents absolute zero. The absolute temperature scale refers to any temperature scale that starts at absolute zero, such as the Kelvin scale. So, the Kelvin scale is a specific type of absolute temperature scale.
What is the temperature at which all molecular motion stops?
This is called absolute zero. The temperature is 0 Kelvin or -273.15 degrees Celsius.
Point where all molecules stop moving?
In theory, all molecular motion ceases at absolute zero which is 0 Kelvin (-273.15 degrees Celsius). At this temperature, the molecules have minimal energy and stop moving completely. However, reaching absolute zero is not practically possible.
What is the lowest temperature that any substance can reach it?
The lowest temperature that any substance can theoretically reach is called absolute zero, which is 0 Kelvin or -273.15 degrees Celsius. At this temperature, particles cease to move due to thermal energy, resulting in a state of minimal energy and entropy. However, achieving absolute zero in practice is not possible due to the third law of thermodynamics.
Is absolute zero is equal to -273 degrees on the Kelvin scale?
Kelvin is defined in such a way that absolute zero is zero Kelvin.Kelvin is defined in such a way that absolute zero is zero Kelvin.Kelvin is defined in such a way that absolute zero is zero Kelvin.Kelvin is defined in such a way that absolute zero is zero Kelvin.
How cold is absolute zero in Celsius?
Absolute zero is -273.15 degrees Celsius and -459.7 degrees Fahrenheit. Kelvin = degrees Celsius + 273.15
What is the zero on the Kelvin scale?
It is Absolute Zero. On the Kelvin scale there are no negative numbers...so therefore absolute zero on the kelvin scale is zero. All we might add is that absolute zero is --273.15 degrees C.
A temperature scale based on absolute zero?
The Kelvin scale is based on absolute zero, the temperature at which all molecular motion ceases. Absolute zero is defined as 0 Kelvin (0 K), which is equal to -273.15 degrees Celsius. On the Kelvin scale, temperatures are always positive and directly proportional to the average kinetic energy of particles in a substance.
How cold is zero kelvin in fahrenheit?
Zero Kelvin is equal to -459.67 degrees Fahrenheit. This temperature is referred to as absolute zero and represents the lowest possible temperature.
Is zero degrees Kelvin absolute temperature?
It is absolute zero.
What is the difference between kelvin and absolute kelvin?
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.
Celsius to kelvin formula?
The Kelvin scale is zero at Absolute Zero ! Absolute Zero is -273C, hence add the Celsius figure to 273 to get the Kelvin figure
What is the special name for zero degree Kelvin?
Absolute zero.
Is absolute zero the point at which a substance has minimal thermal energy?
Yes, absolute zero is the lowest possible temperature where a substance has minimal thermal energy. At absolute zero, the atoms or molecules in a substance stop moving and have no kinetic energy. This temperature is equivalent to 0 Kelvin or -273.15 degrees Celsius.
Can nothing get colder than 0 k?
No,0 Kelvin is absolute zero,cold as anything can get.
Absolute zero is zero on the?
Kelvin Scale.
