Use your data, the equation below, and the specific heat of water (4.184 J/g°C) to compute the specific heat values of each metal. Use a calculator and round to the nearest hundredth place.
$c_{\text{metal}} = \frac{-c_{\text{water}} m_{\text{water}} \Delta T_{\text{water}}}{m_{\text{metal}} \Delta T_{\text{metal}}}$
