Question

SI unit of trmperature is kelvin .define it

Answer 1

The kelvin (abbreviation K), 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
