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`
