The temperature at one of the Viking sites on Mars was found to vary daily

from -90 degree Fahrenheit to -5 degree Kelvins. Convert these

temperatures to Kelvin. *

T = 305.22 K

Explanation: given that

from -90 degree Fahrenheit to -5

degree Kelvins

Using the formula

(9/5 C) + 32 = F

Let's first convert degree Fahrenheit to degree Celsius

90 = 9C/5 + 32

9C/5 = 90 - 32

9C/5 = 58

9C = 290

C = 290/9

C = 32.22 degree Celsius

Convert degree Celsius to Kelvins

T = 273 + C

T = 273 + 32.22

T = 305.22K
