How much heat transfer (in kj) is necessary to raise the temperature of a 0.250 kg piece of ice from −24.0°c to 128°c, including the energy needed for phase changes? (assume the substance remains at a constant volume throughout each stage of the heating process.)

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?  

Heat is involved in chemical change in two ways; chemical changes either result in heat being added to or removed from an object, and chemical changes require a certain amount of heat before they can take place.
