3. According to Newton's cooling law, the rate of cooling of a hot body is pro-portional to the difference between the temperatures of the hot body and theenvironment. If the room temperature is 35°C and the temperature of a hotbody in the room cools down to 55°C from 105°C Celsius in just 6 minutes,then how many more minutes will it take to cool down to 45°C?

According to Newton's cooling law, the rate of cooling of a hot body is pro- portional to the difference between the temperatures of the hot body and the environment. If the room temperature is 350C and the temperature of a hot body in the room cools down to 55°C from 105°C Celsius in just 6 minutes, then how many more minutes will it take to cool down to 45°C?

Newton's Law of Cooling says that the rate at which a body cools is proportional to the differnce C in temperature between the body and the environment around it. The temperature f(t) of the body at time t in hours after being introduced into an environment having constant temperature T0 is f(t)=T0+Ce-kt, where C and k are constants.A pot of coffee with initial tempature of 100°C is set down in a room with a tempature of 20°C.The coffee cools to 60°C after 1 hour. A)Write an equation to model the data. B)Find the tempature after half an hour. C)How long will it take for the coffee to cool at 50°C
Suppose that as a body cools, the temperature of the surrounding medium increases because it completely absorbs the heat being lost by the body. Let T(t) and Tm (t) be the temperatures of the body and the medium at time t, respectively. If the initial temperature of the body is T1 and the initial temperature of the medium is T2, then it can be shown in this case that Newton's law of cooling is dT/dt = k(T - Tm ), k 0 is a constant. (a) The foregoing DE is autonomous. Determine the limiting value of the temperature T(t) as t→ o What is the limiting value of Tm (t) as t→o? (b) Verify your answers in part (a) by actually solving the differential equation. (c) Discuss a physical interpretation of your answers in part (a).
