Question

A 57g metal cube at room temperature is heated to reach 150 °C, then dropped into an insulated container filled with 70 g of water at 20 °C. The final equilibrium temperature for the system (cube and container) is 30.4 °C. What is the specific heat for this cube? A. 0.0071 cal/g·°C B. 0.107 cal/g·°C C. 1.23 cal/g·°C D. 9.36 cal/g·°C
