Question

a body cools at the rate of 1℃ per minute when it is 50℃ above the surrounding.calculate the rate of cooling when it is 30℃ above the same surrounding​

Answer 1

Answer:

Rate of cooling is directly proportional to the temperature difference between the body and the surroundings. For temperature difference.......

$\frac{1}{x} = \frac{50}{30} \\ \\ x = \frac{30}{50} \\ \\ x = \frac{3}{5} \\ x = 0.6$
