Question

A certain freezing process requires room temprature to be lowered from 60 degree Celcius at the rate of 8 degree Celcius every hour . What will be the room temprature , 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
