Question

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Answer 1

SI units or International System of Units is defined as basic set of measurement of seven units. The physical quantities and base units are as follows:

Length is measured in meter (m), mass in kilogram (kg), time in second (s), electric current in ampere (A), temperature in Kelvin (K),  luminous intensity in candela (cd) and amount of substance in mole (mol).

Therefore, SI units of physical quantities is known as base units and other units are known as derived units because they can derived from the SI units.

Thus, the correct match will be:

$Mass\rightarrow kilogram$

$Temperature\rightarrow Kelvin$

$Time\rightarrow second$

$Electric current\rightarrow ampere$

From the rest of the units, degree Fahrenheit is derived unit for temperature, gram is derived unit for mass, nanosecond is derived unit for time and candela is SI unit for luminous intensity.
