Question

The temperature on the Celsius scale is ${25}^{o}C.$ What is the corresponding temperature on the Fahrenheit scale?

• A. ${40}^{o}F$
• B. ${77}^{o}F$
• C. ${50}^{o}F$
• D. ${45}^{o}F$

Answer 1

The correct option is B ${77}^{o}F$

$T_{\left(℃\right)}=25℃$

The relation between $℃$ and $℉$ is $:$

$T_{\left(℉\right)}=T_{\left(℃\right)}\times \frac{9}{5}+32$

$\therefore T_{\left(℉\right)}=25\times \frac{9}{5}+32$

$\therefore T_{\left(℉\right)}=77℉$
