A1.00 kg chunk of an unknown metal that has been in boiling water for several minutes is quickly dropped into an insulating styrofoam beaker containing 1.00 kg of water at 18.0 ∘c. after gently stirring for 5.00 minutes, you observe that the water's temperature has reached a constant value of 22.0 ∘c . the specific heat capacity of water is cw = 4190 j/(kg⋅k) . 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 capacity of the metal cm?
