Which of the following shows the maximum rise in temperature?
23° to 32°
–10° to 1°
–18° to –11°
–5° to 5°
Explanation (step by step):
To find the rise in temperature, use:
( ext{Rise}= ext{Final temperature}- ext{Initial temperature})
(a) 23° to 32°
( ext{Rise}=32-23)
(=9^circ)
(b) –10° to 1°
( ext{Rise}=1-(-10))
(=1+10)
(=11^circ)
(c) –18° to –11°
( ext{Rise}=-11-(-18))
(=-11+18)
(=7^circ)
(d) –5° to 5°
( ext{Rise}=5-(-5))
(=5+5)
(=10^circ)
Conclusion: The largest rise is (11^circ), so the answer is (b).
