Two absolute scale A and B have triple points of water defined to be at `200 A` and `350 B`. The relation between `T_(A)` and `T_(B)` is

Explanation

200 A on absolute scale A corresponds to 272.16 K on Kelvin scale. Size of one degree on absolute scale A in terms of the size of the degree on Kelvin scale = `(273.16)/(200)` .
the value of temperature `T_(A) ` on Kelvin Scale
`( (273.16)/(200)) T_(A)`
Similarly, the value of temperature `T_(B)` on Kelvin scale
`( (273.16)/(300)) T_(B)`.
But , `T_(A) and T_(B)` represent the same temperature `((273.16)/(200))T_(A) = ((273.16)/(300)) T_(B) rArr T_(A) = (2)/(3) T_(B)`
