A 15.0 g copper ring at 0°C has an inner diameter of D = 3.61231 cm. A hollow aluminum sphere at 93.0°C has a diameter of d 3.61852 cm. The sphere is placed on top of the ring (see the figure), and the two are allowed to come to thermal equilibrium, with no heat lost to the surroundings. The sphere just passes through the ring at the equilibrium temperature. What is the mass of the sphere? The linear expansion coefficient...

A brass ring of diameter 10.00 cm at 22.0°C is heated and slipped over an aluminum rod of diameter 10.01 cm at 22.0°C. Assume the average coefficients of linear expansion are constant. (a) To what temperature must the combination be cooled to separate the two metals? -177 °C Is that temperature attainable? Yes (b) What if the aluminum rod were 10.02 cm in diameter? -173.31 Your response differs from the correct answer by more than 10%. Double check your calculations....

A bare copper cable 2.5 cm in diameter is situated in still air at 15°C. A current of 800 Amps is passed along the cable. Heat is transferred from the cable to its surroundings by natural convection for which the heat transfer coefficient may be expressed as 2.95025 W/m2 K. Determine whether or not it may be assumed that the temperature across the copper cross section is uniform and what the equilibrium temperature of the cable surface will be. If...
