A 125 kg metal is submerged to a boiling water for 10.00 minutes. It is quickly dropped into an insulating Styrofoam beaker containing 2.00 kg of water at 25°C. After waiting and gently stirring for 5.00 minutes, you observe that the water’s temperature has reached a constant value of 40°C (a) 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? (b) Which is more useful for storing thermal energy: this unknown metal or an equal weight of SILVER (c = 234 J/kgK) ? Explain in no more than 5 sentences
