Question

Which of the following shows the maximum rise in temperature?

• A. ${23}^{o}to{32}^o$
• B. $-{10}^{o}to{1}^o$
• C. $-{18}^{o}to-{11}^o$
• D. $-5^{o}to{5}^o$

Answer 1

The correct option is B

$-{10}^{o}to{1}^o$

Rise in temperature = Difference between 'Final temperature' and 'Initial temperature'
$\therefore$ Rise in temperature for ${23}^{o}to{32}^o$ is ${32}^o-{23}^o=9^o$

Rise in temperature for $-{10}^{o}to{1}^o$ is $1^o-(-10{)}^o=1^o+{10}^o={11}^o$

Rise in temperature for $-{18}^{o}to-{11}^o$ is $-{11}^o-(-18{)}^o=-{11}^o+{18}^o=7^o$

Rise in temperature for $-5^{o}to{5}^o$ is $5^o-(-5^o)=5^o+5^o={10}^o$

$\therefore$ maximum rise in temperature is for $-{10}^{o}to{1}^o$
