Question

a certain freezing process requires that room temperature be lower from 40 digree celcius at the rate of 5 digree celcius every hour what will be the room temperature ten hours after the progress begin​

Answer 1

Answer:

-10 degree Celsius is right answer

Answer 2

Initial temperature =400C

Rate of change in temperature =50C/hour

Time =10 hours

So, in 10 hours the temperature would be decreased by 10×5=500C

Therefore, the final temperature =40−50=−100C

Hence, this is the answer.
