Question

A difference of $1^{\circ }C$ on a celsius scale equal to ______ ${}^{\circ }F$ on a Fahrenheit scale

Answer 1

We know that $9C=5(F-32)$

Let the temperature in Celsius scale be $C$ and in Fahrenheit be $F$.

$F_1=\frac{9C}{5}+32$

Now when the Celsius scale is increase by 1 , so new temperature is $C+1$.

So $F_2=\frac{9(C+1)}{5}-32$

$F_2-F_1={\frac{9}{5}}^{o}F$
