A platinum resistance thermometer wire has a resistance of 5 ohms at 0^oC and 5.5 ohms at 100^oC. Calculate the temperature of the wire when the resistance is 5.2 ohms

80^oC

60^oC

40^oC

10^oC

Correct answer is C

100^oC .... 5.5

\(\theta\)^oC .... 5.3

0^oC .... 5.0

\(\frac{\theta - 0}{100 - 0}\) = \(\frac{5.5 - 5 .0}{5.5 - 5.0}\)

\(\theta\) = 40^oC
