A plarinum resistance thermometer is condtructed which resds `,0^0` at ice point and `100^0` at steam point. Let t`p denote temoerature on this scale and let t denote the temperature on a metcury on a mercury themomenter  scale. The resistance of the platinum coil vares with `t` as `R_1 = R_0 (1+alphat + betat^2)`. Derive an expression for the resistance as a function of `T_p`.
