## Kelvin scale

n
(General Physics) a thermodynamic temperature scale based upon the efficiencies of ideal heat engines. The zero of the scale is absolute zero. Originally the degree was equal to that on the Celsius scale but it is now defined so that the triple point of water is exactly 273.16 kelvins. The International Practical Temperature Scale (1968, revised 1990) realizes the Kelvin scale over a wide range of temperatures. Compare Rankine scale

## Kelvin scale

A scale of temperature beginning at absolute zero (-273.15°C). Each degree, or kelvin, has the same value as one degree on the Celsius scale. On the Kelvin scale water freezes at 273.15 K and boils at 373.15 K. See Note at Celsius.

## kelvin scale

An absolute temperature scale in which 0 K (zero kelvin) equals -459.67°F (-273.15°C), absolute zero, and 273.15 K corresponds to 32°F (0°C).

If we use 135 C (275 F) as our HDT, which is the midpoint between the two values that appear in the graph, and then calculate this 80% value (ignoring for a moment the proper protocol of doing so on the absolute or Kelvin scale, discussed last month), we obtain a value of 108 C (226 F).
