Question

1. 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 10hours after the process begins?​

Answer 1

Answer:

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
