A solid aluminum sphere (mass 40g and diameter of 2.520 cm) at 100 C is placed on top of a thin steel ring (diameter 2.500 cm) at 20.0 C. The sphere-ring system is placed inside a thermal insulated box (no heat in or out). Find: (a) the final temperature that the solid sphere and the ring have the same diameter. (b) the mass of the ring. Coefficient of thermal expansion alfa of the steel is 8.0x106 1/K, Alpha of the aluminum is 12.0x10-6 1/K. the specific heat of the aluminum is 0.22 cal/g C, and that of the steel is 0.11 cal/g°C.
