A 500 g chunk of unknown metal , which has been in boiling water for several minutes, is quickly dropped into an insulating Styrofoam beaker containing 1.00 kg of water at room temperature (20°C). After waiting and gently stirring for 5.00 minutes, you observed that the water's temperature has reached a constant value of 22. 0 °C. Assuming that the Styrofoam absorbs a negligibly small amount of heat and that no heat was lost to the surroundings, what is the specific heat of the metal?
