Question

A certain freezing process requires the room tempturere be lowered from 55o c at the rate of 5o c every hour what will be the room tempertaure 8 hours after the process begins?

Answer 1

Answer: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
