Two absolute
scales A and B have triple points of water defined as 200A and 350B. If TA
and TB represent same temperature in scale A and B respectively what
is the relation between TA and TB?
Show <=Solution
Triple point of water on scale A = 200 A
Triple point of water on scale B = 350 B
Also, triple point of water on Kelvin scale = 273K
Now temperature on scale A and on scale B is equivalent to 273K on absolute temperature scale.
Thus, value of one degree on absolute scale A = (273/200)K
=> Value of temperature TA on absolute scale A = (273×TA)/200
Similarly value of temperature TB on absolute scale B = (273×TB)/350
Since TA and TB represent the same temperature
Therefore, 273×TA/200 = 273×TB/350
=> 7TA = 4TB
