21. If you have one gram of each of the following metals, which one would you expect to heat up the fastest? A) Silver B) Lead C) Aluminum D) Iron 22. If it requires 67 J of heat to r aise the temperature of a pi ece of iron by 5.0 o C, calculate the mass of the iron. The sp ecific heat of iron is 0.46 J/g o C. A) 150 g B) 100 g C) 29 g D) 706 g 6 Lab Quiz # 2, 3 23. Inside a typical calorimeter the sample releases energy and heat flows into the water. In order to calculate the speci fic heat of an unknown metal, which of the following measurements must be made? A) Mass of the unknown metal, mass of the water, initial tempera ture of the metal, final temperature of the water B) Mass of the unknown metal, mass of the water, initial tempera ture of the metal, initial and final tempe ratures of the water C) Mass of the calorimeter, initial temperature of the metal, in itial and final temperatures of the water D) Mass of the calorimeter, mass of the water, initial and final temperatures of the water 24. In lab a student builds an a luminum âtentâ around the calori metry apparatus. The purpose of the âtentâ is to A) cause the system to heat up. B) allow heat to escape into the surroundings. C) limit the amount of oxygen in the system. D) prevent too much loss of heat to the air. 25. Specific heat can be used, a long with other observations, to determine the identity of a substance because it is A) a physical property. B) a chemical property. C) a measure of heat. D) both a physical and a chemical property. 26. During an experiment to determin e the specific heat of a met al, the student did not fully immerse the hot metal object in t he water bath. How would this error change the calculated specific heat? A) The calculated specific heat would be too low because not all of the heat is transferred to the water. B) The calculated specific h eat would be too high because not al l of the heat is transferred to the water. C) The calculated specific heat would be too high because the ma ss submerged is low. D) The calculated specific heat would be unchanged because it is not dependent on the heat transferred
