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 : The temperature in degree Celsius is,

Explanation :

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

where,

= temperature in Kelvin

= temperature in centigrade

As we are given the temperature in Kelvin is, 2.7

Now we have to determine the temperature in Kelvin.

Therefore, the temperature in degree Celsius is,

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
