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 option: b

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
