Which of the following pairs of scales can yield identical numerical values for the temperature of a body?

Options

  1. AKelvin and platinum
  2. BFahrenheit and kelvin
  3. CCelsius and kelvin
  4. DFahrenheit and Rankine

Correct answer

B. Fahrenheit and kelvin

Step-by-step solution

The relation between the Fahrenheit and Kelvin scales is given by: F - 32 180 = K - 273.15 100 For the two scales to show the same reading, let F = K = x . Substituting this into the equation: x - 32 9 = x - 273.15 5 5x - 160 = 9x - 2458.35 4x = 2298.35 x = 574.59 Thus, the Fahrenheit and Kelvin scales can yield identical numerical values at 574.59 . For Celsius and Kelvin, the relation is K = C + 273.15 , which means they can never be equal. For Fahrenheit and Rankine, the relation is R = F + 459.67 , which means
