4. 5. 6. Set the qwater = -qmetal and solve for the Cmetal. Calculate your average Cmetal. Using the reference value you looked up compare the specific heat that you calculated to Calculate your experimental error: %error = [(CM - Cexp)|/CM] 100 Decay Cesium-137 is 30yrs 1/2x104,08 = 52.04 = 104.08€ -K.30 104,08 -52.04=2in 2=30k
