1.	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 ?
Answer» Solution :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`
