Question

According to the website of the National Aeronautics and Space Administration (NASA), the average temperature of the universe is 2.7 K. Convert this temperature to degrees Celsius.

Answer 1

Answer : The temperature in degree Celsius is, $-270.45^oC$

Explanation :

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

$^oC=K-273.15$

where,

$K$ = temperature in Kelvin

$^oC$ = temperature in centigrade

As we are given the temperature in Kelvin is, 2.7

Now we have to determine the temperature in Kelvin.

$^oC=K-273.15$

$^oC=2.7-273.15$

$^oC=-270.45$

Therefore, the temperature in degree Celsius is, $-270.45^oC$
