Question

Which of the following shows the maximum rise in temperature?

• A. $23°$ to $32°$.
• B. $-10°$ to $+1°$.
• C. $-18°$ to $-11°$
• D. $-5°$ to $5°$

Answer 1

The correct option is B

$-10°$ to $+1°$.

Determine the maximum rise in temperature.

Consider temperature $23°$ to $32°$.

$$\begin{gathered} \mathrm{Rise}=32°-23° \\ =9° \end{gathered}$$

Consider temperature $-10°$ to $+1°$.

$$\begin{gathered} \mathrm{Rise}=1°-\left(-10°\right) \\ =1°+10° \\ =11° \end{gathered}$$

Consider temperature $-18°$ to $-11°$

$$\begin{gathered} \mathrm{Rise}=-11°–(-18°) \\ =-11°+18° \\ =7° \end{gathered}$$

Consider temperature $-5°$ to $5°$

$$\begin{gathered} \mathrm{Rise}=5°-(-5°) \\ =5°+5° \\ =10° \end{gathered}$$

Of all Rises $11$is highest

Hence, the correct choice is Option $\mathrm{B}$.
