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?
52°C
50°C
49°C
46°C
Correct answer is B
Cθ = 50, C0 = 2, C100 = 100
θ | = | Cθ - C0
C100 - C0 |
× | 100 | = | 51 - 2
100 - 2 |
× | 100 |
= | 49
98 |
× | 100 |
θ = 50°C.
