Question

The resistance 𝑅𝜃 of a particular resistance thermometer at a Celsius temperature 𝜃 as measured by a constant-volume gas thermometer is given by

𝑅𝜃 = 50.00 + 0.1700𝜃 + 3.00 × 10−4𝜃2.

Calculate the temperature as measured on the scale of the resistance thermometer which corresponds to a temperature of 60°𝐶 on the gas thermometer.

Answer 1

The resistance reading will be the following:

$$R(60) = 50.00 +0.1700\cdot 60 + 3.00\times 10^{-4}\cdot 60^2 =61.28$$

Answer. $61.28$.
