Abstract: In this experiment, the specific heat and the density of an unknown metal was determined in order to identify the unknown metal. Open Document. A calorimeter can range from very expensive lab ones to coffee styrofoam cups but they are all tightly sealed in order to prevent heat from escaping. Good luck. We setup the calorimeter and got a mass of it just being empty then we got a mass with 30mls of water in it. Once the mass of the unknown metal is recorded, put the metal into the boiling water. This experiment was significant in understanding how heat can be absorbed or released and how using a calorimeter can help measure heat flow. Assume the intial temperature of the metal was the same as the temperature of the water it was boiled in., We, human needs energy to live and for movements. compute the specific heats of each metal.

How can the specific heat of a metal be found using a calorimeter? Background. roasts that hurt and rhyme. To determine heat of reaction (H) from calorimetry measurements. The density of the unknown metal was 6.57 g/mL and was determined using a cylinder and displacement. 5 0 obj Explore how heating and cooling iron, brick, water, and olive oil adds or removes energy. Then measure the mass of the water and reassemble, the calorimeter. The heat capacity per unit mass of a body, called specific heat capacity or more simply specific heat, is used to more directly compare the heat capacity of substances. 3. The reaction is done twice, once to measure the heat of the reaction and again to determine the work done in the system. These three different foods with different measurement of energy contents that participated in this lab are potato chips, popcorns, and raw pasta noodle. When silver crystallizes, it forms face-centered cubic cells. Tomatoes to 100 Celsius in a hot water bath. In the world of physics, the term conduction is usually defined as a form of heat transfer by the way of molecular tension inside an object or material that does not show any individual motion in its entirety (Georgia State University). This is on the account that the specific heat of the unknown metal was, In the lab Which Is Your Metal, we attempted to identify an unknown metal by determining its specific heat capacity. 35 This is one of our shortest labs and they usually take me an hour or less if you read the directions carefully. 11/13/13.

Use the formula in the background information to solve for the specific heat of the metal., To determine the specific heat of a metal and its approximate atomic mass. Cooling it down decreases the amount of kinetic energy and slows the movement down. The experimental enthalpy of reaction 4 can then be found using Hess Law and the enthalpies of reactions 1-3. The density of the unknown metal was 6.57 g/mL and was determined using a cylinder and displacement. Also set up 2 dry Styrofoam cups with a lid aside and add 100 mL We added the heated, Using the formula qmetal = m c T, calculate the specific heat of the metal. Market-Research - A market research for Lemon Juice and Shake. We specialize in online courses, instructional services, and more. Listen The calorimeter is the device used to measure the quantity of heat transferred to or from an object. Name 9 features of the femur that were discussed in the video lecture and study guide that are visible on the anterior surface of the femur. mol). The more heat that is added per gram of substance, the greater the temperature change. 2003-2023 Chegg Inc.
