1) (10 pts) Define the term Adiabatic Calorimeter (just look at each word!) Can you think of an adiabatic calorimeter in your daily life? Draw and label a sketch. 2) (20pts) Cooling a Hot Cup of Coffee or Tea You have two12 oz cups containing a hot liquid at 85C (coffee or tea) on a wooden table. They have the same dimensions, they are not covered and they are made of different materials Glass and Styrofoam. a) Sketch the problem. b) Clearly identify all the heat transfer mechanisms (arrows on figure work well) c) Identify the primary driving forces for heat transfer, and the functional relationship. d) Rank the heat transfer mechanisms in each cup based on their importance for energy loss. In all cases, EXPLAIN your answers. 3) (10pts) Styrofoam TM Cups in a Freezer Two 10oz Styrofoam TM cups of water (one at 80C and the other at 25C ) are put in a freezer at 5C. Which would you expect to freeze first? Explain. NOTE: After the Studio you should look-up the MPemba Effect 1) (10 pts) Define the term Adiabatic Calorimeter (just look at each word!)
