Solution
–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.
