Question 8 Your answer is partially correct. Try again. A 22.0 g copper ring at 0°C has an inner diameter of D = 3.71225 cm. A hollow aluminum sphere at 95.0°C has a diameter of d = 3.72008 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...
