In a refrigerator, electrical energy is converted into mechanical energy by a motor. The motor drives a compressor, and this compresses and heats the refrigerant. Mechanical energy is converted into thermal energy in this process.
The hot refrigerant is cooled in the cooling coils behind or beneath the appliance, and the cooler gas is "sprayed" through an expansion valve connected to the cooling coils inside the unit. The releasing of the pressure of the refrigerant allows expansion, and with expansion comes cooling.
A refrigerator does not produce energy; instead, it uses energy to transfer heat from the interior of the refrigerator to the exterior, creating a cooling effect. The energy source for a refrigerator is typically electricity. It converts electrical energy into a cooling effect through a cooling cycle that involves a compressor, refrigerant gas, and evaporator coils.
The refrigeration process works as follows:
So, while a refrigerator does not produce energy, it uses energy to move heat from the inside of the refrigerator (where it's not wanted) to the outside (where it's expelled into the room), resulting in a colder interior temperature.
Most types of energy work in principle, but usually refrigerators are designed to work on electrical energy; some (designed to not rely on the electrical network) might also have an engine that runs on gasoline or some similar fuel.
A refrigerator is a heat pump - it will pump heat from a colder area to a hotter area. I guess this is in the category "thermal energy".
Usually electrical energy, although it is also possible to have other power sources.
the energy conversion in a refrigerator is electrical energy to cool energy

Yes
Heat itself is a form of energy, so no.
The energy is in the form of sound waves, which are moving air molecules, a form of kinetic energy.
The energy that produces the guitar is the sound energy.sound energy travels in waves.it produce when a material vibrates rapidly.
