Question

a certain freezing process requires that room temperature be lowered from 40°c at the rate of 5°c every hour.What will be the temperature of the room after 10 hours?​

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
