Problem
A 0.30 kg sample of an unknown metal is heated with a 120 W heater for 30.0 s. Its temperature increases from 20.0 °C to 51.0 °C. The accepted specific heat of copper is 385 J kg⁻¹ °C⁻¹. Using the experimental data, calculate the percent error between the measured specific heat and the accepted value.
