Answer : The temperature in Kelvin is, 290 K
Explanation :
S.I : It is known as the international System of Units. It is defined as a scientific method to express the magnitude of the several basics units.
There are seven basic units in the system from which the other units are derived.
The seven base unit are, meter for length, kilogram for mass, second for time, ampere for current, kelvin for temperature, mole for amount of substance and candela for intensity.
The conversion used for the temperature from degree Celsius to Kelvin is:

where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in degree Celsius is, 17
Now we have to determine the temperature in Kelvin.



Therefore, the temperature in Kelvin is, 290 K
