If the body temperature of a person is recorded as 37 degrees Celsius, what is the persons body temperature in k? Round your ans
maw [93]

Answer:

The right answer to this question is: 310k

Explanation:

There's a very good formula that can help us to find this answer, but first, we need to know the temperature scale  in Celsius and Kelvin, there's an image below that will help us gather information.

The formula is quite simple, check it below:

C/5  = K-273/5

putting the values we already have in the formula it would be like this:

37/5 = K-273/5

Cutting out the fives, we can have the final result

37= K-273

37+273 = K

K= 310.
