When heat energy is added, two changes are observed:
Change A: Solid changes to a liquid
Change B: Solid changes directly to a gas.
What are the names for phase changes A and B?
A is freezing and B is condensation.
A is freezing and B is sublimation.
A is melting and B is condensation.
Ais melting and B is sublimation.

The answer is the first option just took the test

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
