The lower fixed part of a faulty thermometer reads 2°C while the upper fixed point is 100°C.
What is the true temperature when the thermometer reads 51°C?
-
A.
52°C -
B.
50°C -
C.
49°C -
D.
46°C
Correct Answer: Option B
Explanation
C(_{theta}) = 50, C(_0) = 2, C(_{100}) = 100
| θ | = | C(_{theta}) – C(_0)
C(_{100}) – C(_0) |
× | 100 | = | 51 – 2
100 – 2 |
× | 100 |
| = | 49
98 |
× | 100 |
θ = 50°C.
