1.	The resistances of a platinum resistance thermometer at the ice point, the steam point and the boiling point of sulphur are `2.50, 3.50 and 6.50 (Omega)` respectively. Find the boiling point of sulphur on the platinum scale. The ice point and the steam point measure `0^@ and 100^@`, respectively.
Answer» Correct Answer - D `t = ((R_t - T_0)/(T_(100) - R_0)) xx 100 = ((6.5 - 2.5)/(3.5 -2.5)) xx 100` = `400^@`.
