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 water on absolute scaleA, T₁ = 200 A

Triple point of water on absolute scale B, T₂ = 350 B

Triple point of water on Kelvin scale, T_K = 273.15 K

The temperature 273.15 K on Kelvin scale is equivalent to 200 A on absolute scale A.

T₁ = T_K

200 A = 273.15 K

The temperature 273.15 K on Kelvin scale is equivalent to 350 B on absolute scale B.

T₂ = T_K

350 B = 273.15

T_A is triple point of water on scale A.

T_B is triple point of water on scale B.

Therefore, the ratio T_A : T_B is given as 4 : 7.
