(challenge)

2.0kg

of solid gold (Au) at an initial temperature of

1000K

is allowed to exchange heat with

1.5kg

of liquid gold at an initial temperature at

1336K

. The solid and liquid can only exchange heat with each other. Once thermal equilibrium is reached, what kind of analysis do you need to perform in order to determine if 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.
