Finding the Specific Heat of a Substance
Specific heat is the amount of energy, measured in joules, needed to raise the temperature of one gram of the substance one Celsius degree. Often applied to metallic elements, specific heat can be used as a basis for comparing how different substances absorb and transfer energy. To measure specific heat in the laboratory, a calorimeter of some kind must be used. AFile Size: 225KBPage Count: 4
Determining Heat Capacity of Water Lab Answers
Heat Capacity of 1 Kg from data collected: Heat Capacity/Mass = 371/0 = 2612 J/Kg/oC. Additional Work. The specific heat capacity of a solid or liquid is defined as the quantity of heat required to change the temperature of a unit mass of a substance through a unit change in temperature.People also askWhat is specific heat measured in?What is specific heat measured in?Specific heat is the amount of energy, measured in joules, needed to raise the temperature of one gram of the substance one Celsius degree. Often applied to metallic elements, specific heat can be used as a basis for comparing how different substances absorb and transfer energy.Finding the Specific Heat of a SubstanceSee all results for this questionWhat is the specific heat of lead?What is the specific heat of lead?The heat gained by the water is equal to the heat lost by the metal. This allows for the calculation of the specific heat of the metal. A sample of lead was determined to have a specific heat of 0 cal/g0C. The accepted value for lead is 0 cal/g 0C, which is a 64.5% error.Experiment 15: Specific Heat of a MetalSee all results for this questionWhat is the equation for heat energy?What is the equation for heat energy?For a body of mass m to experience a temperature change of ΔT the heat energy required (Q) is given by the first law: Q=mCv!T+!W Equation(1) In the equation given above, ΔW is the work done by the system on its environment. For the entirety of the lab, the work performed will be zero.Lab 15. Heat CapacitySee all results for this questionHow was the specific heat of two metals determined?How was the specific heat of two metals determined?The specific heat of two metals was determined experimentally. The technique utilized was calorimetry. A sample of each metal was massed and then heated in a hot water bath. The hot metal was then poured into a known quantity of water in a calorimeter. The amount of heat gained by the water was calculated.Experiment 15: Specific Heat of a MetalSee all results for this questionFeedback
Determination of Specific Heat - ScienceGeek
Calculate the value for Q water, using the known values of m water, ΔT water and the specific heat of water, 4 J/(g·°C). Remember that ΔT = (T 2 - T 1 ). Do this for each trial, recording your results in the table.[PDF]
