1. Mechanical energy is used to push or pull the window open.
2. Some of the mechanical energy is converted into potential energy as the window is lifted or moved into an open position.
3. Some of the mechanical energy is also converted into sound energy as the window moves against the frame or makes noise when opening.
4. Some of the mechanical energy is converted into thermal energy as friction between the window and the frame causes heat to be generated.
5. Once the window is open, potential energy is converted into kinetic energy as the window moves freely in the open position.
