Question

According to Newtons law of cooling, the rate at whichsubstance coolsin the air is directly proportional to the difference between the temperature of the substance and that of the air. if the temperature of the air is 30degrees and the substance cools from 100degrees to 70degrees in 15 minutes, how long will it take to cool from 100degrees to 50degrees

Answer 1

Answer:

Newton's law of cooling states that the rate of change of the temperature of an object in proportional to the difference between its own temperature and the ambient temperature ( i.e.the temperature of its surroundings). Newton's law makes a stetement about an instant aneous rate of change of the temperature
