Answer 2

Answer:

Temperature -SI unit :Kelvin

Explanation:

Kelvin is the SI unit of Temperature .

• Don't get confused and write Celsius as the SI unit .Celsius is not the SI unit .

$\\ \sf\longmapsto 1K=273°C$

Or

$\\ \sf\longmapsto 1°C=273.16K$

Lets take an example :-

• Take 27°C

Lets convert to Kelvin scale

$\\ \sf\longmapsto 27°C$

$\\ \sf\longmapsto 27+273$

$\\ \sf\longmapsto 300K$

• SI unit of Mass=kilogram(Kg)
• SI unit of Time=second(s)
• SI unit of electric current=Ampere(A)
