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...
