1. To determine whether a shiny gold rock is actually gold, a student decides to measure its heat capacity. She first weighs the rock and finds it has a mass of 4.7g. She then finds that upon absorbtion of 57.2 J of heat, the temperature of the rock rises from 25 degree Celsius to 57 degree Celsius. Find the specific heat capacity of the substance composing the rock and determine whether the value is consistent with the rock being pure gold. 2. q = m X Cs X temperature change Cs of gold = 0.128 J/g x Celsius 3. 4.7g X 0.128 J/g x C X 32 C = 19.25 c = 9/temperature change = J/C = 57.2/32 C 4.7g X 32 C / 57.2 J Actual solution: 57.2 J / 4.7g X 32 C So my question is; why is 57.2 divided by the others, when if you had brought it over from the other side, wouldn't you divide it BY 57.2?
