The process of nuclear fusion involves a change in density as lighter atomic nuclei combine to form heavier nuclei, releasing a large amount of energy in the process. This is the process that powers the sun and other stars.

The energy change in an electric buzzer involves converting electrical energy to sound energy by causing a diaphragm or other vibrating element to produce sound waves, creating the buzzing sound. This process involves a transformation of energy from electrical to mechanical and acoustic forms.
When energy changes from one form to another, it goes through an energy conversion process. This process involves the transformation of energy from one type to another, such as potential to kinetic or electrical to thermal energy.
The energy change of an electrical saw involves converting electrical energy from an outlet into mechanical energy to power the saw's blade. This process involves the transformation of one form of energy to another to enable the cutting action of the saw.
Density and volume do not directly impact the ability to change energy. Energy change is mainly influenced by the temperature and the specific properties of the material, rather than its density or volume. However, changes in volume can affect the pressure and work done by a system, which may indirectly impact energy transfer.
Convection is the process by which energy is transferred in gases and liquids. It involves the movement of the fluid due to differences in density caused by temperature variances. Warmer, less dense fluid rises, while cooler, denser fluid sinks, creating a continuous circulation to transfer heat energy.
