Question

According to The temperature in degrees Celsius is 32 less than the Fahrenheit temperature, multiplied by five ninths. The temperature in degree Kelvin is the number of degrees Celsius plus 273.

find the temperature in degrees Kelvin when the temperature is 23° F.

  1. 268° K
  2. 258° K
  3. 248° K
  4. 278° K

Hint:

K = 5 over 9 (F - 32) + 273
Substitute the value of 23 to F and compute

The correct answer is: 268° K


    Given F = 23°
    K = 5 over 9 (F - 32) + 273
    K = 5 over 9 (23 - 32) + 273 = -5 + 273 = 268°
