Percent Error In Specific Heat Determination


Then use the integrating factor method, to find the exact value of y(0.1). Please help, I just need to know the basic formula my book didn't provide any examples. September 22, 2010 by Anonymous Chemistry I need to calculate the valueof Kc for 5 test tubes for an experiment that I completed on determination of Kc. Your question isn't complete? navigate here

Show calculations. We now recognize that the thermal energy content of a substance is the total kinetic energy of the particles within it. If the actual specific heat of an unknown metal is 0.25 J/g degree Celsius, what is the percentage error? That's why it is used in many calorimetry experiments.

How To Calculate Percent Error In Chemistry

You just became Owlfred's fan. State what effect it would have on the percentage error calculated for the comparisons. Dry any spills on the table and floor. 6. Please upload a file larger than 100x100 pixels We are experiencing some problems, please try again.

Use 10 OwlBucks to get Qualified Help. When a body gains or loses energy in a thermal process, we find experimentally that the temperature change of the body is proportional to its change in energy: [3] ΔH = Once it is determined, this number is simply added to the measured mass of water, for the purposes of calculation of the heat transfer equation: [8] (mw + meq)(T2 - Tf) Determining The Specific Heat Of A Metal Lab Answers Would the specific heat value have been too high, or too low?
