Water 63

Water was heated at the rate of 6°c per minute for 14 minutes. It then cooled at the rate of 8°c per minute. What will be its temperature after 24 minutes if its original temperature was 40°c?

Correct answer:

t =  20 °C

Step-by-step explanation:

t1=40 °C t2=t1+6 14=40+6 14=124 °C t3=min(100,t2)=min(100,124)=100 °C  t=t38 (2414)=1008 (2414)=20°C
