12. A 0.7-g piece of copper is heated and fashioned into a bracelet. The amount of energy transferred by heat to the copper is 69,800 J. If the specific heat of
copper is 390 J/g°C, what is the change of the copper's temperature?

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
