Two absolute scales `X` and `Y` assigned numerical values `200` and `450` to the triple of water. What is the relation between `T_(X) ` and `T_(Y)` ?

Options

A. (a)`9T_(X)= 4T_(Y)`
B. (b)`4T_(X)= 9T_(Y)`
C. (c)`T_(X) = 3T_(Y)`
D. (d)None of these

Answer

A

Explanation

If we take two fixed points as tripe point of water and `0K`. Then `(T_(X)-0)/(200) = (T_(Y)-0)/(450) implies 450 T_(X) = 200. T_(Y) implies 9T_(X) = 4T_(Y)`
