Tashia & Tobi Lab Report experiemt 5 INTRODUCTION In this experiment we were wanting to find the specific heat of an unknown metal and determining what metal it was by using the formula q=c X m X change of temperature. We did two trials to compare the two and see what we come up with. EXPERIMENTAL First we chose an unknown metal‚ in which our unknown was unknown metal 2‚ the metal was gray and irregular shaped. We setup the calorimeter and got a mass of it just being empty then we got

Heat pump From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search For theoretical background‚ see Heat pump and refrigeration cycle. Outdoor components of a residential air-source heat pump A heat pump is a machine or device that transfers thermal energy from one location‚ called the "source‚" which is at a lower temperature‚ to another location called the "sink" or "heat sink"‚ which is at a higher temperature. Thus‚ heat pumps moves thermal energy opposite to the direction that

Internal Combustion Engines for the Future Horst Schulte‚ Martin Wirth Ford Motor Company ABSTRACT Future internal combustion engines for light duty applications will have to cope with a very complex set of customer‚ legal and business requirements. Customers are expecting further improvements in durability‚ reliability‚ drivability‚ fuel economy‚ and cost of ownership. Legal requirements are focused on significant emission and fuel consumption reductions. Additional manufacturing cost reductions

Objective: To determine the concentration and equilibrium constant for a reaction of colored product using absorption spectroscopy‚ to create a calibration curve for determining equilibrium concentrations by applying Beer’s law and to force the completion of a reaction by applying Le Châtelier’s principle. Procedure: A diluted solution was made from the stock of 0.0025 M Fe(NO3)3 by diluting 4.0 mL to exactly 100.00 mL‚ using serological pipet and volumetric flask. The concentration of the diluted

Heat of Neutralization Introduction: The purpose of this experiment was to measure‚ using a calorimeter‚ the energy changes accompanying neutralization reactions. In order to measure the amount of heat produced by a reaction‚ an instrument called a calorimeter was used. The calorimeter used in this experiment was somewhat rudimentary. It was constructed as shown in the following picture: After finding the heat capacity of the calorimeter‚ the student and partner neutralized two acids and

Group name: Alkali metal Color: Silvery white/grey Lithium is solid only about half as dense as water and lithium metal is the least dense metal. Lithium is known as losing its electron‚ so it becomes Li+. Lithium is mixed with aluminum and magnesium for light-weight alloys and is used in batteries‚ some greases‚ some glasses‚ and in medicine. Lithium is not made in laboratory since it’s so readily available commercially. 4. Beryllium Name: Beryllium Atomic #: 4

conducted to find the specific heat of a metal as well as the heat of solution of a solid. Both experiments required the use of calorimetry to measure heat flow and temperature change. The specific heat of the metal was found by heating it in boiling water before transferring it to the calorimeter that was partially filled with water. After shaking the calorimeter‚ the temperature change was measured and recorded. This information was used to calculate the specific heat. The heat of solution of a solid

Heat exchanger A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids‚ between a solid surface and a fluid‚ or between solid particulates and a fluid‚ at different temperatures and in thermal contact. In heat exchangers‚ there are usually no external heat and work interactions. Typical applications involve heating or cooling of a fluid stream of concern and evaporation or condensation of single- or multicomponent fluid streams. In a few heat exchangers
