Question

Which of the following shows the maximum rise in temperature?

Options

• 0°C to 10°C

• –4°C to 8°C

• –15°C to –8°C

• –7°C to 0°C

Answer 1

–4°C to 8°C

Explanation:

We know that, the maximum rise in the temperature is equal to the maximum value of difference of two temperatures.

a. Difference of 0°C to 10°C

= 10°C – 0°C

= +10°C

b. Difference of –4°C to 8°C

= 8°C – (–4°C)

= 8°C + 4°C

= +12°C  ...[Maximum]

c. Difference of –15°C to –8°C

= –8°C – (–15°C)

= –8°C + 15°C

= +7°C

d. Difference of –7°C to 0°C

= 0°C – (–7°C)

= 0°C + 7°C

= +7°C

Hence, the –4°C to 8°C shows the maximum rise in temperature.
