Question

the AC cools the room at rate of 5°C per hour what is final temperature of the room after 6 hours ,if the initial temperature of the room is40°C

​

Answer 1

Answer:

10 degree C

Explanation:

Initial temp = 40 degree C

Temp. lowered in 1 hour = 5 degree C

                                         = (-5) degree C

Temp. lowered in 6 hours = 6 * (-5) = (-30) degree C

Final temp. = 40 degree C + (-30) degree C  =  10 degree C
