Question

A certain freezing process requires the room temperature be lowered from 40℃ at the rate of 5℃ every hour What will be the temperature 10 hrs after the process ​

Answer 1

Initial Temperature = 40° C
Rate of change in temperature = 5°C/hour
Time = 10 hours

So, in 10 hours the temperature would be decreased by 10*5 = 50°C.

So, Final Temperature = 40 - 50 = - 10°C
