Imagine that you place a piece of copper with an initial temperature of 20°c in contact with some liquid water with an initial temperature of 100°c. assume that the physical system consisting of the copper and the water is thermally isolated from everything else; i. e., they can only exchange energy with each other.
a) sketch two three-phase diagrams, one for each substance, and mark the initial state for each one. explain in a sentence or two how you can tell if either substance will undergo a phase change during the process of coming to thermal equilibrium. you do not need to do any calculations.
