Question

A certain freezing process requires that room temperature be lowered from 32°C at the rate of 5°C every hour. What will be the room temperature 8 hours after the freezing process begins? ​

Answer 1

Answer:

Initial Temperature = 32° C

Rate of change in temperature = 5°C/hour

Time = 8 hours

So, in 8 hours the temperature would be decreased by 8×-5=-40

So, Final Temperature = = 32°-(-40°)= 32+40= 72
