Two ideal gas thermometers A and B use oxygen and hydrogen respectively. The following observations are made :

What is the absolute temperature of normal melting point sulphur as read by thermometers A and B ?

Explanation

Suppose absolute temperature at meting point of sulphur is T.
For thermometer A :
`(T_(A))/(T_(tr))=(P_(A))/(P_(tr))`
`:.T_(A)=T_(tr)xx(P_(A))/(P_(tr))`
`=(273.16xx1.797xx10^(5))/(1.250xx10^(5))`
`=392.69K`
For thermometer B :
`(T_(B))/(T_(tr))=(P_(B))/(P_(tr))`
`:.T_(B)=T_(tr)xx(P_(B))/(P_(tr))`
`=(273.16xx0.287xx10^(5))/(0.2xx10^(5))=391.93K`
