Correct Answer: Option C
Explanation:
100oC .... 5.5
\(\theta\)oC .... 5.3
0oC .... 5.0
\(\frac{\theta - 0}{100 - 0}\) = \(\frac{5.5 - 5 .0}{5.5 - 5.0}\)
\(\theta\) = 40oC
100oC .... 5.5
\(\theta\)oC .... 5.3
0oC .... 5.0
\(\frac{\theta - 0}{100 - 0}\) = \(\frac{5.5 - 5 .0}{5.5 - 5.0}\)
\(\theta\) = 40oC
