An aluminum can of mass 500 g contains 117.5 g of water at 20 C. A 200 g block of iron at 75 C is dropped into the can. Determine the equilibrium temperature of the system. A 0. 010 kg silver bullet is traveling at 200 m/s when it & strikes the tin badge of the town sheriff. The bullet stops on impact with 0. 050 kg badge. If the badge absorbs 60% of the heat evolved during the collision, what is the temperature increase of the badge? 3 If 0. 250 kg of water at 10.0.C is mixed with 0:400 kg of water at 80.0.C, what is the final temperature of the mixture? 4. A 0.200 kg block of iron is heated to 300 C and is placed into water at 0 c. If the final temperature of the system is 85 C, what is the mass of the water? 5 A 1 kq piece of zinc at 71 degrees C is placed into a container of water of mass 20 kq at 10 degrees C. What is the final. . temperature of the system? 0 . 2
