Question 23

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

Rise in temperature,
(a) ${32}^o-{23}^o=9^o$
(b) $1^o-(-10{)}^o=1^o+{10}^o={11}^o$(maximum)
(c) $-{11}^o-(-18{)}^o=-{11}^o+{18}^o=7^o$
(d) $5^o-(-5^o)=5^o+5^o={10}^o$
