There are two models which explain the effect of composition on thermal properties. Assume you know the composition of each product and, in the case of layered products, the composition of each layer. Draw a diagram of the product, specify the boundary and initial conditions, and then outline how you would estimate the products overall thermal conductivity: A cherry at field temperature (25°C) was suddenly placed in cold water at 5°C. A French fry is rapidly immersed in a deep fat fryer containing cooking oil at 400°C. A chicken breast is rapidly immersed in a deep fat fryer containing cooking oil at 450°C. An unbaked apple turnover was placed in an oven at 300°C.
