A superhero is building a suit of armor made of Vibranium (Vb). To mold the headpiece of this suit, he need to heat 1 kg of the metal into its forging temperature. Its forging temperature must be at least 70% of its melting point in Kelvin (MPyB = 3297 K). Assuming that the melting point and the forging temperature of Vb can be achieved, answer the following questions. a. Determine the specific heat capacity (J/kg-°C) of Vb if it loses 519.2775 kJ as it is being cooled from its melting point down to its forging temperature. b. The newly forged headpiece is then submerged in 2.5 L of liquid water initially at room temperature. Since the headpiece is still at its forging temperature right before it was submerged in water, some of the water vaporized in the process. What is the volume (L) of the remaining liquid water if the headpiece and the remaining water are in thermal equilibrium at 50 °C?
