Question

Q1 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 room temperature 10 hours after the
process begins?​

Answer 1

Step-by-step explanation:

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
