Applications of First-order Differential Equations, 1 Newton’s law of cooling states that the rate of fall of temperature is proportional to the excess of the temperature of a body over that of the surrounding space. If . is the temperature of the body and . that of the surrounding space, write down the differential equation and integrate it.
