Temperature
The phase diagram of substance X is shown above. Initially, X is at
point C. After a significant increase in pressure, X is at point B. What
phase change has X gone through?

Limited time please help!!

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

What are the choices?
