Conceptual Questions: These questions are to be answered with a short para- graph. Problem 1. In a calorimetry experiment, 3 samples A, B, and C with T1 > T B > To are placed in thermal contact. When the samples have reached thermal equilibrium at a common temperature T, which one of the following must be true?: (a) QA > QB > Qc (b) QA 0 ((1) T > TB ((1) T T > To Problem 2. Two objects with the same mass are heated to the same temperature. They are placed into identical insulated water baths that are initially at room temperature. The nal temperatures of the water baths with the objects in them are di'erent. Would the bath with the higher nal temperature contain the object with the greater or the lesser specic heat? (Assume the initial ten'lperatures of the objects are greater than room temperature) Complete Solution Questions: These problems are to be answered with detailed calculations. Problem 3. Two bricks are made of the same material, but brick 1 has half the volume of brick 2. The two bricks have initial tenmeratures T1 : 300C and T2 = 60C, respectively. They are placed next to each other and exchange heat. What is the nal equilibrium ternperaturer.' Neglect heat losses to the environment. Problem 4. A copper piece of mass 140 g and of temperature 24000 is placed into 360 g of water at temperature 25061 . Find the nal equilibrium temperature. Neglect the heat losses to the environment. Problem 5. 50.0 g of ice at 720.000 is placed in a glass containing 100 g of liquid water at 100C. Assume that there is no heat transfer from the water to the glass or to the environment. How much ice melted? Extra Problem 1. Two brieks are made of aluminum and iron, respectively. They have the same number of atoms. Which one requires more heat for raising its temperature by 10 K"? Extra Problem 2. How much heat is required te raise the temperature of 250 g of water from 80.0"C to 1200C\"? Extra Problem 3. Calculate the nal temperature and phase when 100;; of iee at 5.00"C is mixed with 200;} of water at 20.000. Assume no heat is transferred between the mixture and the surrounding
