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?
What is the true temperature when the thermometer reads 51°C?
52°C
50°C
49°C
46°C
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.
