Because on the Celsius (aka Centigrade) scale, zero is defined as the freezing point of water at standard pressure. On the Kelvin ( aka absolute ) scale zero is defined as the lowest temperature possible - not relative to water or any other substance.

∙ 14y agoTemperature is a measure of the vibrational energy of an atom. Vibration gives rise to pressure of a gas and hence it's volume. Reducing the temperature slows this atomic vibration and the volume shrinks proportionately. At zero degrees Kelvin the gas volume will be zero which is not possible. Therefore there can be no temperature where a negative volume of gas exists.Hence the term absolute zero and the impossibility of ever reaching it, you can only approach it.(half of a half of a half etc)

Absolute zero. Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance. Absolute zero is the point at which the fundamental particles of nature have minimal vibrational motion, retaining only quantum mechanical, zero-point energy-induced particle motion

What is the temperature scale used in the metric system?
Everyday temperature is measured in degrees celcius. Officially temperature is measured in kelvin. the only difference between kelvin and degrees celcius is that zero kelvin is absolute zero ( the coldest theoretical temp possible) and zero degrees celsius is the triple point of water. So that 0oC is 273.15 kelvin.
How are degrees Celsius converted to kelvins?
One degree Celsius equals one degree Kelvin, so the only issue is where the scales are indexed, or, if you prefer, where zero is. For Kelvin, it's at absolute zero. (That way all temperatures in K are positive.) For Celsius, it's at the freezing point of water.Celsius:Zero ºCelsius is 273.15 KelvinKelvin:Absolute Zero is -273.15 ºCelsiusanother way to know is that its converted by adding 273 to degrees Celsius.Use this equation to convert Celsius/Centigrade to degrees Kelvin: [K] = [°C] + 273.15
What is larger 1 K or 1 c?
If you're talking about Temperature, then 1C is warmer. 1K is only one Kelvin above absolute 0, while 1C is one degree Celsius above the freezing point of water. One Kelvin and One degree Celsius are equal in value.
What is the volume of the gas before and after cooled?
The volume of a gas - at constant pressure - is proportional to the absolute temperature, that is, to the temperature expressed in Kelvin. This relationship is only approximate for real gases, but it is close enough for most practical purposes.
Why is the SI unit of temperature Kelvin but not Celsius?
Celsius and Fahrenheit are relative scales which are compared with freezing and boiling points of water. While kelvin is not relative and is an absolute scale. From graphical representation of Charles's when one extrapolate the graph straight, it will touch the zero volume at -273.16 Celsius or OK. This OK is the start or emergence of kelvin scale which is not related to anything, but absolute.
Each degree on the Kelvin scale equals?
The relationship between Kelvin and Celsius scale is K=C+273. 15. Where K is Kelvin temperature and C is Celsius temperature. Each degree on the Kelvin scale equals the same degree in Celsius scale differing only in the zero value. The freezing point of water and absolute zero are the zero values of Celsius and Kelvin scale respectively.
What scale is the same as the celsius scale?
Kelvin. Both Celsius and Kelvin are measurements of temperature in the metric system, and both have the same size of degree. The only difference between them is that Kelvin has been shifted down the scale so that 0 degrees Kelvin is absolute zero, the coldest possible temperature.
Which two temperatures do you use for absolute zero?
There is only one temperature for absolute zero, but it can have different numbers in different scales, for example 0 kelvin, or -273.15 degrees Celsius.

What is BE Condensate?
BE condensate is the state of matter below solids, like plasma is above gases. It only occurs at absolute zero(0˚ Kelvin, -273.15˚ Celsius, -459.67˚ Fahrenheit) or for some elements a few billionths of a Kelvin degree above absolute zero.
What do the Celsius and Kelvin temperature scales have in common?
Both are used to measure temperature. A difference of 1 degree is the same in both scales. The only difference is the starting point. The lowest possible temperature (absolute zero) is 0 Kelvin; this is equivalent to 273.15 degrees Celsius. Thus, on the Kelvin scale there are no negative temperatures, by definition.
Why do scientists use the Kelvin and Celsius scale rather than the Fahrenheit scale?
Celsius is a very accurate measurement between the freezing and boiling points of water. 0 being freezing, and 100 boiling. Kelvin is the measurement of absolute zero, where particles stop moving altogether. Kelvin has the same conversion rating, only 0 Kelvin is -273 degrees Celsius. The Kelvin scale is an absolute scale. This means that 2 K is twice as hot as 1 K and so on. Neither the Celsius nor the Fahrenheit scales do that. The Centigrade (or Celsius scale are based on the freezing and boiling points of water (at normal pressure), the Fahrenheit scale was not: the 0 was the lowest temperature attained by ice and salt.

What is measured in Kelvins or degrees Celsius?
Kelvin is just a unit x*c+273.1=1KelvinAnswerIn thermodynamics, certain equations are based on temperatures being measured relative to absolute zero. In these cases, the kelvin temperature scale must be used. Examples include the equations relating to Charles' and Boyle's Laws. Elsewhere, the kelvin scale is used simply because it is the SI unit for temperature, and Celsius can easily be used in its place.
Why only 273 kelvin why not 280 kelvin?
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?"
What do you mean by 1 degree celsius of rise in temperature equal to 1 kelvin of rise in temperature of a substance?
1 kelvin and 1 celsius degree are both exactly the same thing ... a unit of temperature, equal to 1/100 of the difference between the freezing and boiling points of water. The only difference between the Kelvin scale and the Celsius scale is that they start from different temperatures ... the Celsius number starts from the freezing point of water, whereas the Kelvin scale starts from 'absolute zero'. So the Kelvin temperature will always be 273.15 more than the Celsius temperature ... because it starts at 273.15 lower. But when the temperature changes by some number of Celsius degrees, it changes by exactly the same number of Kelvins, because 1 Kelvin is exactly the same size as 1 Celsius degree.
