Question

Use the given specific heat capacity values below to calculate the percent error of the experimental specific heat capacity that you determined in Part I of the lab.

Known specific heat values — Iron: 0.444 J/g°C; Zinc: 0.390 J/g°C; Copper: 0.385 J/g°C, Aluminum: 0.900 J/g°C


| experimental - actual value | x 100 %
actual value

Answer 1

Well, what values for the specific heat capacities after your experiment?
This question fits better into the Physics section.

Answer 2

0.4 and 0.42 are my values

Answer 3

These are for which substances?

Answer 4

They are both nickel

Answer 5

Well,consider only one value(that would be the average of the two values you got). Now get the actual value for the specific heat capacity of Ni.(you can get that from wikipedia-just search 'nickel'). Now, find the difference of these two values, and divide it by the actual value. Multiply that by 100.
That's your error percentage.
Did you get it?

Answer 6

i figured it out thanks1

Answer 7

yes, it more to physics i think..

Answer 8

In complete sentences, describe three sources of experimental error that could occur with this type of calorimetry lab. Explain, in detail, the effect that each specific error would have on the calculated specific heat capacity values.

Answer 9

Basically they are asking what could change the outcome of the experiment
