(challenge) 2.0 kg of solid gold (Au) at an initial temperature of 1000K is allowed to exchange heat with 1.5 kg of liquid gold at an initial temperature at 1336K. The solid and liquid can only exchange heat with each other. What kind of analysis do you need to perform in order to determine whether, once thermal equilibrium is reached, the mixture will be entirely solid or in a mixed solid/liquid phase? Calculate the final amount of solid and liquid gold. Draw two separate Temperature vs. Energy added diagrams to help you answer this question. Molar mass of
