Q. 11.4 Answer the following :
(d) What is the temperature of the triple-point of water on an absolute scale whose unit interval size is equal to that of the Fahrenheit scale?
Let at a certain temperature the reading on Fahrenheit and Kelvin Scale be TF and TK respectively
Let at another temperature the reading on Fahrenheit and Kelvin Scale be T'F and T'K respectively
Subtracting equation (ii) from (i)
For TK - T'K = 1 K, TF - T'F = 9/5
Therefore corresponding to 273.16 K the absolute scale whose unit interval size is equal to that of the Fahrenheit scale
