What are the energy changes in a Piston which starts at rest, rises slowly and then comes to rest?

According to the law of conservation of energy, the total energy in a closed system is conserved.

Considering the energy changes in the Piston X and Y:

Gravitational potential energy of piston X: the gravitational potential energy of the Piston X decreases as it's height above the oil decreases.

Gravitational potential energy of piston Y: The gravitational potential energy of Piston Y increases as it is pushed upward due to the downward movement of Piston X.

Chemical energy of piston Y: the chemical energy of Piston Y remains unchanged since no chemical change occurs.

Kinetic energy of piston Y: the kinetic energy of Piston Y starts from zero, then increases to a maximum before returning to zero when it comes to rest.

Therefore, the energy changes that occurs in Piston X and Y are:

gravitational potential energy of Piston X decreases
gravitational potential energy of Piston Y increases
chemical energy of Piston Y remains unchanged
kinetic energy of Piston Y starts from zero and then increases before returning to zero.
