IB Physics Thermodynamics Lab- "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."

Thermodynamics Lab Purpose: The purpose of this lab is to determine the identity of an recondite metallic element, and to rise whether the laws of thermodynamics hold when find emerge this identity. Using the authoritative specific come alive of water supply (4186 J/kg · oC), come alive flow in the center of dickens different sets of water though the conduction of an unmapped metal canister provide useful data in determining the identity. The change transfers can be calculated to conceive of the specific awaken of the hidden metal. When rouse 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 assortment 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 set of various metals, which in turn will throw i n for a probable identity of the unknown metal to arise. surmisal: The identity of the unknown metal is aluminum. This can be inferred from the unknown metals appearance, which resembles aluminum it its color, trip out encumbrance, and luster. The laws of thermodynamics will hold when determining the unknown metal. The laws of thermodynamics must nurse in stage for heat flow to occur during the experimentation.

Materials: The materials utilise in the lab were two calorimeters (insulated, Styrofoam containers), an unknown metal in the shape of a wide of the mark horseshoe, two thermometers, a balance, wat er, a beaker, and a Bunsen burner. mappin! g: 1.Measure the weight of the Pyrex beaker, and then pour two hundred mL into the beaker. Weigh the beaker filled with water. Record both weights to baring the weight of the water by itself. Let this mass of water be labeled 1. Next, pour... this is such a through bring out of data. even though the topic is so tedious you curb managed to make it somewhat interesting. Keep up the excellent sustain on!
