AP EAMCET · PHYSICS · Thermal Properties of Matter
If the values of the temperature of a body in Fahrenheit and Celcius scales are in the ratio of \(13: 5\), then the temperature of the body is
- A \(80^{\circ} \mathrm{F}\)
- B \(104^{\circ} \mathrm{C}\)
- C \(40^{\circ} \mathrm{C}\)
- D \(40^{\circ} \mathrm{F}\)
Answer & Solution
Correct Answer
(C) \(40^{\circ} \mathrm{C}\)
Step-by-step Solution
Detailed explanation
\( \frac{F}{C} = \frac{13}{5} \Rightarrow F = \frac{13}{5} C \) \( \frac{C}{5} = \frac{F-32}{9} \) \( \frac{C}{5} = \frac{\frac{13}{5}C-32}{9} \) \( 9C = 5(\frac{13}{5}C-32) \) \( 9C = 13C - 160 \) \( 4C = 160 \) \( C = 40^{\circ} \mathrm{C} \)
