Question

Find out which of the following shows the maximum rise in temperature?

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

Answer 1

The correct option is B

$-4^{\circ }C$ to$8^{\circ }C$

Option (a) : $0^{\circ }C$to${10}^{\circ }C$

The change in the temperature is the difference between the two temperatues.

${10}^{\circ }–0^{\circ }={10}^{\circ }C$

Option (b): $-4^{\circ }C$to$8^{\circ }C$

The change in the temperature is given by

$8^{\circ }-(-4^{\circ })={12}^{\circ }C$

Option (c) :$-{15}^{\circ }C$to $-8^{\circ }C$

The rise in the temperature is given as

$-8^{\circ }-(-{15}^{\circ })=7^{\circ }C$

Option (d): $-7^{\circ }C$to$0^{\circ }C$

The difference in the temperature is calculated by

$0^{\circ }-(-7^{\circ })=7^{\circ }C$

The maximum rise in the temperature is an option (b) i.e. ${12}^{\circ }C$

Hence, option (b) is the correct answer.
