Question

A certain freezing process require that room temperature be lowered from 40c at the rate of 5c every hour what will be the room temperature 10 hours after the process beign? ​

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

Answer 2

Given: Present room temperature = 40°C Decreasing the temperature every hour = 5°C Room temperature after 10 hours = 40°C + 10 x (–5°C ) = 40°C – 50°C = – 10°C Thus, the room temperature after 10 hours is – 10°C after the process begins.
