What is the basis for the kelvin scale?

Answer 1

AnswerA Kelvin scale is a scale used for measuring temperature in scientific expirements.

By: a grade 7

The kelvin scale has exactly the same degrees as the centigrade scale HOWEVER the position of zero on the kelvin scale is set at -273.15 on the centrigrade scale.

So if water freezes at 0'C it freezes at 273.15 K

and if water boils at 100'C it boils at 373.15'K

The Kelvin scale was made so that equations such as the ideal gas law could be expressed both simply and elequently.

PV=nRT

without the need of fudge factors

PV=nR(T+273.15)

As a small addition, the Kelvin scale is based on absolute zero. Zero Kelvin is the absence of all heat and no colder temperature is theoretically possible.

The Kelvin scale was developed by William Thomson - a.k.a. Lord Kelvin - and the markings on the scale are not called degrees, but are simply called kelvins.

(0o Celsius is equal to 273.15o Kelvin)

Answer 2

Lord Kelvin based the Kelvin scale as zero degrees K being cessation of all molecular motion. We now know that reaching absolute zero may never bee accomplished, in our time (2007) we have apparatus that can reach within a few tenths of a degree of zero K.

Answer 3

The Kelvin (abbreviated K) scale measures temperature just like Celsius or Fahrenheit.

0 K is the lowest possible temperature on the Kelvin scale, where everything stops moving. It's absolute zero, and theory says if the temperature of something was at that temperature, the small molecules in that something wouldn't move at all.

Besides that, the Kelvin scale and Celsius scale work well together. To convert kelvin to Celcius, simply subtract 273.14. (I.E. 273.14K = 0 deg. C.)

Answer 4

The Kelvin scale is a temperature scale that sets its zero point to absolute zero. This is different from the Celsius scale where zero is the freezing point of water which is measured to be about 273.15 kelvin.

Answer 5

-- The degrees are the same size as Celsius degrees, i.e. 100 of um between ice and boiling water.

-- Kelvin zero is at absolute zero . . . 273.15 degrees lower than Celsius zero.

-- It's named for Lord Kelvin, whose laboratory was apparently always cold.

Answer 6

The Celsius scale is based on the freezing and boiling points of water. Water freezes at 0 degrees Celsius, and boils at 100 degrees Celsius.

Answer 7

Celsius 0 degre and kelvin -273 degre celsius

Answer 8

Mercury

Answer 9

It is the Sl unit for temperatur
