Question

If two temperatures differ by 25 degrees on Celsius scale, the difference of temperature on Fahrenheit scale is

• A. ${65}^o$
• B. ${45}^o$
• C. ${38}^o$
• D. ${25}^o$

Answer 1

The correct option is B ${45}^o$

${}^{o}F=\frac{g}{s}{(}^{o}C)+32$

Then, two temperatures differ in Florentine scale

$\Delta {}^{o}F=\frac{g}{s}\left(\Delta {}^{o}C\right)$

$\Delta {}^{o}F=\frac{g}{s}\left(25\right)={45}^o$.
