MHT CET · Physics · Thermal Properties of Matter
A centigrade and Fahrenheit thermometer are dipped in boiling water. The water temperature is lowered until the Fahrenheit temperature observed is \(140^{\circ} \mathrm{F}\). At that time the temperature registered by the centigrade thermometer is
- A \(80^{\circ} \mathrm{C}\)
- B \(60^{\circ} \mathrm{C}\)
- C \(40^{\circ} \mathrm{C}\)
- D \(20^{\circ} \mathrm{C}\)
Answer & Solution
Correct Answer
(B) \(60^{\circ} \mathrm{C}\)
Step-by-step Solution
Detailed explanation
\(C = \frac{5}{9}(F - 32)\) \(C = \frac{5}{9}(140 - 32)\)
