Which of the following pairs of physical quantity and SI unit is correct ?

A. Mass - SI unit : Gram

B. Time - SI unit : Hour

C. Electric current - SI unit : Volt

D. Temperature - SI unit : Kelvin

Answer 1

Temperature -SI unit :Kelvin

Step-by-step 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)
