Question

Two absolute scales A and B have triple points of water defined to be 200 A and 350 B. What is the relation between T_A and T_B ?

Answer 1

Triple point of the water at absolute scale =273.15 K

Triple point of water on scale A =200A

Triple point of water on scale B =350 B

Value of the temperature T A on absolute scale A = 273.15 200 T A

Value of temperature on absolute scale B = 273.15 350 T B

Since T A and T B are at same temperature, therefore

273.15 200 T A = 273.15 350 T B T A = 200 350 T B T A = 4 7 T B
