The temperature of a 0.555 kg block of ice is lowered to -120°C. Heat (0.5159 MJ) is then transferred to the block of ice (assume ice is otherwise thermally isolated). What is the final temperature of the water in °C?​

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
