In this problem you will consider the effect that thermal expansion due to temperature will have on Archimedes' principle. Take the densities of water and copper at 0ºC to be 1.00 × 103 kg/m3 and 8.90 × 103 kg/m3, respectively. a.  Calculate the fraction of a copper block’s weight that is supported by the buoyant force at 0°C.  b. Calculate the fraction of a copper block’s weight that is supported by the buoyant force at 95°C. Assume the volume expansion coefficient of copper is βC = 5.10 × 10-5 1/°C.
