This lab is based on items you have in your house. Each lab counts for 20 points and it is about 1.42% of the total grade, each little point counts, do not miss it!Items that you needed for these two activities 1. Three insulated cups (same type) 3 2. Chopsticks (or any non-metallic stirrers 2)3. Hot water 4. Stopwatch and a camera 5. A metal spoon, a wooden pencil, a plastic pen, or a glass rodActivity 1 (12 points) Take two insulated cups, partially fill them with equal amounts of cold water, and drop equal amounts of ice into each cup to obtain a mixture of ice and water. (a) Stir the water and ice mixture in one of the cups vigorously with a nonmetallic stirrer until all of the ice has melted. Write down the time it takes to melt the ice and add a picture of your experiment below (3 points) [Answer](b) Set the second cup aside and observe it every 10 minutes or so until all the ice has melted. Write down the time it takes for the ice to melt. (2 points) [Answer](c) How do the times compare? Describe your observations clearly in the given space (2 points) [Answer](d) Where is the energy coming to melt the ice in each cup? Using the first law of thermodynamics, explain how the internal energy of the ice is increased to melt it. (5 points) [Answer]Activity 2 (8 points)Fill an insulated cup with very hot water (or Coffee). Take objects made of different materials, such as a metal spoon, a wooden pencil, a plastic pen or a glass rod. Put one end of each object into the water. Add a picture your setup below (2 points) [Picture]Answers to following questions (a) How close to the surface of the water do you have to hold the object for it to feel noticeably warm to the touch? Discuss three different objects. (2 points) [Answer](b) From your observations, which material would you judge to be the best conductor of heat? Which is the worst? (2 points) [Answer](c) Rank the materials according to their ability to conduct heat from best to worst. (2 points) [Answer]
