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?
find the temperature change of the water, δtw, and that of the metal, δtm.
