COMEDK · Physics · 12. Thermal Properties of Matter
The temperature at which centigrade and Fahrenheit scales give the same reading, is
- A \(-40^{\circ}\)
- B \(40^{\circ}\)
- C \(-30^{\circ}\)
- D \(30^{\circ}\)
Answer & Solution
Correct Answer
(A) \(-40^{\circ}\)
Step-by-step Solution
Detailed explanation
Using relation, \[ \frac{F-32}{180}=\frac{C}{100} \quad \text{...(i)} \] If \(F=C=x\), then substituting value of \(\mathrm{Eq}\). (i), we get…
