Answer : The correct option is, Its density increase.

Explanation :

The melting is the process in which the phase changes from solid state to liquid state at constant temperature that is 0^oC .

As we know that the structure of solid water is cage-like structure. From the cage-like structure the density of solid water is less. When temperature increases the solid water starts melting and its density increases but at that time the composition of water does not change, it remains same only changes takes place in the phase.

From the given options we conclude that the density increases to water when it is heated from 0^oC to 4^oC temperature.

Hence, the correct option is, Its density increase.

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
