1090 words - 4 pages

Thermodynamics LabPurpose:The purpose of this lab is to determine the identity of an unknown metal, and to prove whether the laws of thermodynamics hold when determining this identity. Using the accepted specific heat of water (4186 J/kg · oC), heat flow between two different sets of water though the conduction of an unknown metal can provide useful data in determining the identity. The heat transfers can be calculated to approximate the specific heat of the unknown metal.When heat is transferred to an object, the temperature of the object increases. When heat is removed from an object, the temperature of the object decreases. The relationship between the heat (q) that is transferred and the change in temperature (DT) is: q = mCDT = mC · (Tf - Ti).After the specific heat of the metal is found, it can then be compared to known specific heat values of various metals, which in turn will allow for a probable identity of the unknown metal to arise.Hypothesis:The identity of the unknown metal is aluminum. This can be inferred from the unknown metal's appearance, which resembles aluminum it its color, light weight, and luster. The laws of thermodynamics will hold when determining the unknown metal. The laws of thermodynamics must apply in order for heat flow to occur during the experimentation.Materials:The materials used in the lab were two calorimeters (insulated, Styrofoam containers), an unknown metal in the shape of a wide horseshoe, two thermometers, a balance, water, a beaker, and a Bunsen burner.Procedure:1.Measure the weight of the Pyrex beaker, and then pour 200 mL into the beaker. Weigh the beaker filled with water. Record both weights to find the weight of the water by itself. Let this mass of water be labeled '1'. Next, pour the water into one of the calorimeters and take the temperature of it. This temperature should be the room temperature and the same as the unknown metal's temperature.2.Pour 200 mL of water into the beaker and weigh the beaker filled with water. Record the weight. Let this mass of water be labeled '2'.3.Use the Bunsen burner to heat up the 200 mL of water in the beaker to 75o C. Then pour the hot water into the other calorimeter.4.Set-up the calorimeters by placing the thermometers and the unknown metal in their specific places.5.Record temperatures of both calorimeters every minute until thermal equilibrium is reached.6.Clean and return all materials and dispose of any waste.Data Tables:Masses of ObjectsItemBeakerBeaker w/ water (1)Beaker w/ water (2)Unknown MetalMass (nearest .0001 kg).1696 ± .0001 kg.3686 ± .0001 kg.3878 ± .0001 kg.2104 ± .0001 kgNote: '1' à the water that was at room temperature'2' à the water that was heated to 75o CTemperature Changes During Heat Transfer Per MinuteElapsed Time (in minutes and ±1 min.)Temperature of '1' (nearest 1 oC and ± 1 o C)Temperature of '2' (nearest .5 o C and ± .5 o C)122 o C75.0 o C223 o C75.0 o...

746 words - 3 pages . and the final temperature of the system was 26C. We can determine the specific heat and which metal it was. We start of by organizing our data into a table:Heat gained by the waterHeat lost by the metalMass of water  100 Mass of metal (m)  24Initial temperature of water  22.2ºCInitial temperature of metal - 100ºCFinal temperature of mixture - 26ºCFinal temperature of mixture - 26ºCT  3.8 T  74And get an equation:100*4.184(26-22.2) = 100*C*(100-26)Solve for C and get the specific heat to be:0.214 JApplication:Radon has the lowest SHC with .094 J/gK.Hydrogen is the highest with 14.307 J/gK.
