TS EAMCET · Physics · Thermal Properties of Matter
The temperature on a Fahrenheit temperature scale that is twice the temperature on a Celsius temperature scale is
- A \(160^{\circ} \mathrm{F}\)
- B \(240^{\circ} \mathrm{F}\)
- C \(320^{\circ} \mathrm{F}\)
- D \(480^{\circ} \mathrm{F}\)
Answer & Solution
Correct Answer
(C) \(320^{\circ} \mathrm{F}\)
Step-by-step Solution
Detailed explanation
Temperature on Fahrenheight \(\mathrm{F}=\frac{9}{5} \mathrm{C}+32\) Given \(F=2 C\) or \(C=F / 2\) \(\therefore \mathrm{F}=\frac{9}{5} \times \frac{\mathrm{F}}{2}+32 \Rightarrow \mathrm{~F}-0.9 \mathrm{~F}=32 \therefore \mathrm{~F}=320^{\circ} \mathrm{F}\)
