(a) Suppose that 0.100 kg of liquid copper is supercooled to 250 K, where it is allowed to nucleate and solidify adiabatically (no heat is lost to the surroundings). Calculate how much copper will solidify until the temperature recalesces to its melting point of 1356 K. The specific heats of solid and liquid copper in the temperature range of interest are respectively:
