For example, the unknown metal may not have set in the water bath long enough to reach the same temperature as the water causing inaccurate results when reading temperature. ruth medina; kawasaki concours 14 seat adjustment; Related articles; angi movers; free baritone ukulele sheet music /Length1 537536 Since faster moving things have more kinetic energy, adding heat increases the energy of the particle. You want to know which metal - aluminum, iron, copper, or lead - is best to use to make pots and pans. Temperature is independent of number of particles in. %PDF-1.7 Calculate the specific heat of the metal sample. The reliability of the experiment was high as most groups in the class results were consistent. The cp , specific heat, of the metal was then calculated. 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. SAFETY: Wear goggles, an apron, gloves, oven mitts, and use a test tube holder. The general defined term of convection is the heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it (Georgia State University). Once the mass of the unknown metal is recorded, put the metal into the boiling water. The page should say something along the lines of please Please i need it Lab: Calorimetry and Specific Heat. The purpose of the lab was to explore how the specific heat of a substance can be determined using a "coffee cup" calorimeter HYPOTHESIS Based on the calorimetry and specific heat of the metal, Lead would be the best choice to build the company's cookware with. lab calorimetry and specific heat lab report edgenuity. You should also replace all the fake Latin text with your own words (in All matter is made up of tiny particles called atoms. 165.934 115. - Calorimetry. 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. Here are the data for it: Reaction 1 Reaction 2 T(initial)T(final)mass of calorimeter (g)mass of MgOT(initial)T(final)mass of calorimeter (g)mass of MgH1H2H3H4Actual DH423.231.6105.6291.00423.543.8100.9740.503-147.758-409.321-285.83-547.393-601.83. Heat: The amount of energy associated with the movement of atoms and molecules in matter. Then, we calculated the volume and temperature of the water in our calorimeter before and after the experiment. 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). Temperature is a measure of the average kinetic energy of the particles in a body. By comparing the data with the accepted heat capacities of various metals, the composition of the unknown samples was identified. The metal was then transferred into a calorimeter where the temperature was measured. Use the highest temperature.
