Question

100 K = _____ -173°C 0°C 100°C 373°C

Answer 1

100 k= -173°c...............

Answer 2

Answer : The correct option is, $-173^oC$

Explanation :

The conversion used for the temperature from Kelvin to degree Celsius is:

$K=273+^oC$

where,

K = temperature in Kelvin = 100 K

$^oC$ = temperature in degree Celsius = ?

Now put the value in the above conversion, we get the temperature in degree Celsius.

$100=273+^oC$

$^oC=100-273$

$^oC=-173$

Therefore, the temperature in degree Celsius is, $-173^oC$
