cooling machine requires that room temperature to be lowered from 50�

1.	cooling machine requires that room temperature to be lowered from 50째C at the rate of 5째Cery hour. What will be the room temperature after 6 hours, after process begins?
Answer» Initial Temperature = 40° CRate of change in temperature = 5°C/hourTime = 10 hours So, in 10 hours the temperature would be decreased by 10*5 = 50°C. So, Final Temperature = 40 - 50 =- 10°C

Answer»

Initial Temperature = 40° CRate of change in temperature = 5°C/hourTime = 10 hours

So, in 10 hours the temperature would be decreased by 10*5 = 50°C.

So, Final Temperature = 40 - 50 =- 10°C
