I'm working on a lab and I need to determine the percent error, does anybody know how to do this. For the lab we had to find the specific heat capacity of brass by putting it in boiling water and then cold water and look at the temperature change.
Thank-you, that sounds and looks correct when I do it all. I was forgetting to subtract the theortical so I was getting 62%, but it was supposed to be -38%.
found at http://www-ee.uta.edu/ Percent Error = Theoretical Value - Experimental Result Theoretical Value X 100 hope this helps
lol im guessing this is high school math xD so complicated, but i cant wait to start doing it. just curious, what exactly do you use that for?
Not math, physics. We had to do a lab to determine the specific heat capacity of a metal. Then we had to calculate how much our error was. Because we already know what the specific heat capacity should be. Specific heat capacity is the amount of energy it takes to heat a substance that weighs 1kg 1oC. So like water is 4200J/kgoC.
