Newton's Law of Cooling The temperature, u, of a heated object at a given time t can be modeled by the equation u(t) = T+ (uo - T)et where k < 0 is a constant, T is constant ambient temperature, and up is the initial temperature of the heated object. Suppose that an object has been heated to 90 degrees celsius and is then allowed to cool in a room that is kept at a constant 45 degrees celsius. If the temperature of the object is 73 degrees celsius after 8 minutes, when will its temperature be 58 degrees celsius? minutes.
What is the rate of heat transfer in J/s through the body's skin and the fat layer just beneath its surface? Treat the skin and fat as a single layer that is 1.20 cm thick. Assume the temperature of the inner surface of the layer corresponds to internal body temperature, or 36.7 °C, and the temperature of the outer surface of the layer corresponds to skin temperature, or 34.0 °C. Take the total surface area of the layer to be 1.50 m² and use a value of 0.413 W/(m-C°) for the average thermal conductivity of the layer. Number Units

Suppose you perform an experiment using the Celsius temperature scale and find a change in temperature of 5°C. Then you perform the same experiment again now using the Kelvin temperature and you have a temperature change of 5 K, you can state that: a) the kelvin temperature change is greater. b) these temperature changes cannot be compared with each other. c) the change in the Celsius temperature scale is greater. d) both temperature changes are equal.
We know from Newton's Law of Cooling that the rate at which an object warms up is proportional to the difference between the ambient temperature of the room and the temperature of the object. The differential equation corresponding to this situation is given by y' = k(M – y) where k is a positive constant. The solution to this equation is given by y = M + (yo – M)e-kt , where yo is the initial temperature of the object. Suppose your Thanksgiving turkey is kept at a temperature of 40 degrees Fahrenheit until it is put into a 350 degree Fahrenheit oven. It takes 2 hours for the turkey to warm up to a safe eating temperature of 165 degrees Fahrenheit. Find the values of yo, M, and k, for this situation, rounding your answers to 3 decimal places. Yo= M = k= Regardless of your answers above, suppose the k value in this situation is k = 0.3. Find the initial rate of increase of the turkey's temperature as soon as it is placed in the oven.

You happen to come across a piece of metal that has a density of p 8.12 g/cm3 when the temperature is To = 42.5 °C. If the metal is cooled to a temperature of T1 0.00 °C, does the density change? Yes, the density will decrease since the volume changes. Yes, since the metal contracts and the mass is constant, the density will increase. No, because as the volume changes so does the mass. No, density does not depend on temperature. Calculate the density of the piece of metal at this temperature, P1. The coefficient of volume expansion for this piece of metal is B = 7.62 x 10-5 1/°C. -0.0263 Pi = g/cm3 Incorrect
