Question

A temperature difference of ${30}^{\circ }C$ in the Fahrenheit scale will be :

• A. ${54}^{\circ }F$
• B. ${27}^{\circ }F$
• C. ${86}^{\circ }F$
• D. $-{54}^{\circ }F$

Answer 1

The correct option is A ${54}^{\circ }F$

${30}^{0}C={30}^0\times \frac{9}{5}+32={86}^{0}F$
The temperature difference of ${30}^{0}C$ in the Fahrenheit scale is $86-32={54}^{0}F$
hence,option A is correct.
