Question

Newton's Law of Cooling Newton formulated the principle that the rate of change of the temperature of an object is proportional to the difference between the object's temperature and the temperature of the surroundings. 1. (a) Suppose that the temperature of an object at time \( t \) is given by \( T(t) \). Denote the surrounding temperature \( T^{*} \), and assume it is constant. Write down a differential equation expressing Newton's Law of Cooling: \[ \frac{d T}{d t}= \] \( \qquad \) \( \qquad \) Note that if the surrounding temperature is greater than the temperature of the object, we expect the temperature of the object to \( \qquad \) , whereas if the surrounding temperature is lower than the temperature of the object, we expect the temperature of the object to \( \qquad \) . Given that we usually take our constants of proportionality to be positive, does your equation above reflect this? If not, correct it.
