The rate at which a body cools also depends on its exposed surface area S. If S is a constant, then a modification of (2), given in Section 3.1, is dT kS(T-Tm). where k < 0 and Tm is a constant. Suppose that two cups A and B are filled with coffee at the same time. Initially, the temperature of the coffee is 160° F. The exposed surface area of the coffee in cup B is twice the surface area of the coffee in cup A. After 30 min the temperature of the coffee in cup A is 110° F. If Tm80° F, then what is the temperature of the coffee in cup B after 30 min? (Round your answer to two decimal places.) F

In winter, a canal in Canada has an ice layer on its surface. The depth from the surface to the bottom of the canal is 2.2m. If the temperature of the air above the ice is-5.4 °C and the temperature of water at the bottom of the canal is 3.9 °C, what would be the thickness of the ice layer? (Please write your answer in the box without rounding. Write what you see on the calculator up to two decimal points WITHOUT UNIT.)
The goal in this problem is to find the growth of an ice layer as a function of time. Call the thickness of the ice layer L. (a) Derive an equation for dL/dt in terms of L , the temperature T above the ice, and the propertiesof ice (which you can leave in symbolic form instead of substituting the numbers). (b) Solve this differential equation assuming that at t = 0 , you have L = 0. If you have studied differential equations, you will know atechnique for solving equations of this type: manipulate the equation to get dL/dt multiplied by a (very simple) function of L on one side, and integrate both sides with respect to time. Alternatively, you may be able to use your knowledge of the derivatives of various functions to guess the solution, which has a simple dependence on t. (c) Will the water eventually freeze to the bottom of the flask?

Samples A and B are at different initial temperatures when they are placed in a thermally insulated container and allowed to come to thermal equilibrium. Figure (a) gives their temperatures T versus time t. Sample A has a mass of 4.79 kg; sample B has a mass of 1.50 kg. Figure (b) is a general plot for the material of sample B. It shows the temperature change AT that the material undergoes when energy is transferred to it as heat Q.
