  • question_answer What temperature is the same on celsius scale as well as on Fahrenheit scale?

    A)  \[-\,212{}^\circ C\]                  

    B)  \[-\,40{}^\circ C\]  

    C)  \[-\,32{}^\circ C\]            

    D)         \[32{}^\circ C\]

    Correct Answer: B

    Solution :

     \[\frac{C}{5}=\frac{F-32}{9}\,\,Here\,\,C=F\] \[\frac{C}{5}=\frac{F-32}{9}\Rightarrow 9C=5C-160\]\[4C=-160\Rightarrow C=-{{40}^{o}}C\]  Thus at \[-\,40{}^\circ C\] and \[-\,40{}^\circ F\] the temperature is same.
