The resistances of a platinum resistance thermometer at the ice point, the steam point, and the boiling point of sulphur are

2.50\ \Omega

3.50\ \Omega

, and

6.50\ \Omega

, respectively. Find the boiling point of sulphur on the platinum scale. The ice point and steam point measure

0^\circ\text{C}

and

100^\circ\text{C}

, respectively.
