A 50.0 g iron rod is heated to an unknown initial temperature. While cooling down to a temperature of 25.0 ºC, the rod releases 300.1 J of energy. The specific heat of iron is 0.452 J/g ºC and the density is 7.87 g/cm3. If the mass of the iron were increased to 100. grams: Group of answer choices   A. The density and specific heat would increase. B. The density, specific heat and energy released would stay the same C. The volume of the iron and the heat capacity would increase. D. The density, specific heat and energy released would all increase.
