Answer 1

Given,

Temperature at 12 noon = 10°C

Final temperature = -8°C

Decrease in temperature = 10-(-8)=18°C

Time taken for the temperature to decrease by 2°C=1 hour

Time taken for the temperature to decrease by

18°C=1/2×18=9 hours.

Now,

Time until mignight =12 hours

Decrease in temperature in 12 hours=2×12=24°C

Therefore, temperature at midnight=10-24=-14°C

Therefore, temperature at mid-night will be

below zero.
