The lower fixed part of a faulty thermometer reads 2^\circC while the upper fixed point is 100^\circC.
What is the true temperature when the thermometer reads 51^\circC?
A
52°C
B
50°C
C
49°C
D
46°C
Verified Correct Answer: B.
Physical Principles & Numerical Solution
C\(_{\theta}\) = 50, C\(_0\) = 2, C\(_{100}\) = 100
\theta
=
C\(_{\theta}\) - C\(_0\)
C\(_{100}\) - C\(_0\)
\times
100
=
51 - 2
100 - 2
\times
100
=
49
98
\times
100
\theta = 50^\circC.
