Abstract: In this experiment, the specific heat and the density of an unknown metal was determined in order to identify the unknown metal. Two unknown metals were put in boiling water for two minutes to ensure thermal equilibrium. All three participants are all flammable. endobj A metal sample weighing 45.2 g and at temperature of 100.0 C was placed in a calorimeter containing, Overall, the experiment succeeded that the metals show the theoretical properties. T water. A calorimeter is an apparatus for measuring the amount of heat that is involved with chemical reaction or in any other process. Edgenuity is a leading provider of K-12 online curriculum and blended learning solutions. The overall field of thermodynamics involves the study of thermal processes in physical systems. In our physical world, there are a multitude of phenomenon that occur daily that we experience that often go unnoticed. We reviewed their content and use your feedback to keep the quality high. We added the heated, Using the formula qmetal = m c T, calculate the specific heat of the metal. Record the temperature of the boiling water on the hot plate with the metal and then record the temperature of the water in the coffee cup before adding the metal. Introduction: Calorimetry is the art of measuring energy.For example, determining how Our unknown metal got identified by calculating the heat change and we came to the result that we were using copperand ion metals. q = mcT. Chemistry questions and answers. We heated the 300ml of water to a boil, then placed the metal that was in a tube and waited 10 minutes before we took it out. Table 1. Using the short fiber optic cable, record the O-scope display of **Do not forget to hand this in before leaving class! 2 C2H6(g) + 7 O2(g) 4 CO2(g) + 6 H2O(l). << Commercial solution calorimeters are also available. The temperature of the water before the metal was placed in was 21 degrees Celsius and then when the metal was heated up for 10 minutes the temperature went up to 28 degrees Celsius. The reason is because it takes more energy to increase the kinetic energy of hydrogen-bonded water molecules than it does for substances in which the dominant intermolecular interaction is the much weaker van der Waals force. The change in heat can tell us if the reaction is either exothermic - it released or heat into surroundings, or endothermic - it absorbed heat from surroundings. The metal was placed in a test tube 5cm high and we got the mass of the empty test tube that was 42.703g and then with the metal in it and it was 72.607g. compute the specific heats of each metal. Is it possible to find the specific heat of unknown metals using calorimetry? Assignment: Response Mechanism of Invertebrate You will not be able to type into the document until you save your own. T = T final T initial. Wear goggles, an apron, gloves, oven mitts, and use a test tube holder. 8 0 obj Purpose: To utilize a calorimeter correctly to find the enthalpy changes in two different reactions. The amount of thermal energy in a substance is affected by the amount of particles that are in it. When heat is added to a substance, the kinetic energy of individual particles increases, which makes them move faster resulting in a increase in temperature. Some or very little heat was lost from the metal cup due to surrounding environment. mol). The page should say something along the lines of please Please i need it Lab: Calorimetry and Specific Heat. How can the specific heat of a metal be found using a calorimeter? Specific heat is the ability of any material to retain heat energy is called that material's heat capacity. Experts are tested by Chegg as specialists in their subject area. Step 4: Once the water is boiling . The measure of heat capacity, or the quantity of heat needed to raise the temperature of one gram of a substance by one degree Celsius, is termed specific heat and is represented by the symbol s, Cp, c. The SI units for specific heat are given in J/gC. Calculate your percent error. temperature of the tap water.

If Motrin contains 0.8 g of ibuprofen in a 500 mL bottle, what is the concentration of This is one of our shortest labs and they usually take me an hour or less if you read the directions carefully. Let me know if youve shared it. We began by choosing a sample of metal, finding its mass, and describing it. :), For the electronic transition from n=2 to n=4 in the hydrogen atom. We subtracted them two and we got the mass of water was 49.176g. Background. Enter the email address associated with your account, and we will email you a link to reset your password. The more heat that is added per gram of substance, the greater the temperature change. This lab includes three burning tests of different foods with different energy contents. Apply to become a tutor on Studypool! Use scientific instruments to record measurement data in appropriate metric units that reflect . The lab also uses distilled water, which is water purified by a process of heating and cooling. What was the temperature change for the metal sample (Tmetal)? Some were variable and some were constant. The calorimeter is the device used to measure the quantity of heat transferred to or from an object. Then, use the equations to see the relationship between change in energy and the amount of substance involved. This causes the temperature of the water to increase. This one should help you a lot more. 2 0 obj Edgenuity has created an inviting, interactive learning environment to help guide you toward academic success and recover credits to help you graduate more quickly. Two polystyrene coffee cups; Lid for polystyrene cup; Thermometer . Ini"al temperature of water is the room Q w = -Q s Where Q is the change in heat. It is assumed that the specific heat capacity is constant in the temperature range, although in reality it does vary with temperature., c. 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. The following data was obtained from a calorimeter experiment: The specific heat of beryllium is _____ J/gC 0.124 0.549 1.82 9.61 9520, The lab procedure involves several factors, listed below. Specific heat values are also commonly given in cal/gC, where 1 calorie=4.184 Joules. The purpose of the lab was to explore how the specific heat of a substance can be determined using a coffee cup calorimeter. YOUR CLASS (Chemistry in the Earth System A). Through these calculations, we determined that the heat transferred to the calorimeter water from the hot metal was 595.65J (6.0x10J with proper significant figures). of water in calorimeter "C Initial temp.

Pure water has high specific heat capacity that is exactly 1 calorie per gram, whereas other common substances have much lower specific heats. Some terms involved with these particular concepts include: closed system, empirical law, free energy, joules law, specific, temperature, and thermodynamics. Finally, equations 1, 2 and 3 can be combined into the calorimetry equation: ( 5 ) Use the highest temperature. Repeat the experimental procedure three more, Using this specific heat value of the unknown metal and the density of the unknown metal, it was determined that the unknown metal was Tin. SC-Chemistry SC Academic . Based on the calorimetry and specific heat of the metal, Lead would be the best choice to build the companys cookware with. You can find the enthalpy of formation of water in the NIST database here. It is an intensive property, as opposed to the heat capacity, which is an extensive property that depends on the amount of substance present. Once the mass of the unknown metal is recorded, put the metal into the boiling water. 23rd May 2016. Explore information provided by the CDC, WHO, literary source a for a total of at least 5 sources.
