H5: Mixing un-like materials Materials: copper cylinder with hole, hot water, temperature probes, grabber for moving the cylinder, styrofoam cups, room temp water Initial Instructions and questions: Get equal masses of copper and room temperature water. You can probably get a more accurate mass of water by weighing it than by using the measuring cylinder. You will be heating up the copper and then putting it into the room temperature water to determine the equilibrium temperature. At this point make a prediction. Do you think the equilibrium temperature will be the average temperature or closer to one of the initial temperatures? Give your reasoning. Scratch a distinctive mark on the top of your cylinder so you can keep track of it. Use the grabber to carefully place your copper cylinder into one of the two coffee makers. Leave it for at least 10 minutes so that it reaches equilibrium with the water. After 10 minutes, fill a Styrofoam cup half full of hot water from the coffee maker
