Question

A certain freezing process requires the i
o process requires the room temperature be lowered from 35°C at the
rate of 7°C every hour. What will be the temperature at the end of 10th hour.​

Answer 1

Initial Temperature = 35° C

Rate of change in temperature = 7°C/hour

Time = 10 hours

So, in 10 hours the temperature would be decreased by 10*7 = 70°C.

So, Final Temperature = 35- 70 = - 35°C
