Question

Which of the following shows the maximum rise in temperature?

• A. $-4^{0}C$ to $8^{0}C$
• B. $-{15}^{0}C$ to $-8^{0}C$
• C. $-7^{0}C$ to $0^{0}C$
• D. $0^{0}C$ to ${10}^{0}C$

Answer 1

The correct option is A $-4^{0}C$ to $8^{0}C$

A. $0^{0}C$ to ${10}^{0}C$
Difference in temperature = ${10}^{0}C-0^{0}C$
$={10}^{0}C$

B. $-4^{0}C$ to $8^{0}C$
Difference in temperature = $8^{0}C-(-4)0C$
$=8^{0}C+4^{0}C$
$={12}^{0}C$

C. $-{15}^{0}C$ to $-8^{0}C$
Difference in temperature $=-8^{0}C-(-15{)}^{0}C$
$=-8^{0}C+{15}^{0}C$
$=7^{0}C$

D. $-7^{0}Cto-0^{0}C$
Difference in temperature $=0^{0}C-(-7{)}^{0}C$
$=0^{0}C+7^{0}C$
$=7^{0}C$

${12}^{0}C$ is the maximum rise in temperature among the given options.
Hence, the correct option is B.
