Question

a certain freezing process requires that room temperature be lowered from 40 degree Celsius at the rate of 5 degree Celsius every hour what will be the room temperature 10 hour after the process begins

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

Answer 2

Answer:

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
