Kelvin Scale used for measuring Temperature
Answers
Answer:
temperature is measured by kelvin scale
Answer:
The kelvin less commonly called the degree Kelvin (symbol, o K), is the Standard International ( SI ) unit of thermodynamic temperature. One kelvin is formally defined as 1/273.16 (3.6609 x 10 -3 ) of the thermodynamic temperature of the triple point of pure water (H 2 O).
The kelvin scale differs from the more familiar Celsius or centigrade ( o C) temperature scale; there is no such thing as a below-zero Kelvin figure. A temperature of 0 K represents absolute zero, the absence of all heat. However, the size of the kelvin "degree" is the same as the size of the Celsius "degree." A change of plus-or-minus 1 o C is the same as a change of plus-or-minus 1 K.
At standard Earth-atmospheric sea-level pressure, water freezes at 0 o C or +273.15 K, and boils at +100 o C or +373.15 K. A temperature of 0 K thus corresponds to -273.15 o C. A temperature of 273.15 K corresponds to 0 o C. To convert a kelvin temperature figure to Celsius, subtract 273.15. To convert a Celsius temperature figure to kelvin, add 273.15.
