Question

Which of the following pairs may give equal numerical values of the temperature of a body?
(a) Fahrenheit and Kelvin
(b) Celsius and Kelvin
(c) Kelvin and Platinum

Answer 1

The pair which may give equal numerical values of the temperature of a body is (Fahrenheit and Kelvin).  

Explanation:  

• If we consider  $T_{F}$  and $T_K$   as the temperatures measured in Fahrenheit and Kelvin scales respectively, then  $T_{F}=T_{K}=\theta=574.59^{\circ}$ where, θ is the temperature in Fahrenheit and Kelvin scales.  But in case of Celsius and Kelvin scales, such θ does not exist.
• Also, in Kelvin and Platinum scales, they depend on properties of thermometric substance used to define the scale.  
• Hence, such value does not exist in Kelvin and Platinum.

Answer 2

Answer:

Fahrenheit and Celsius/ Kelvin and platinum
