What energy transformations occur in a hairdryer?
Motor action occurs when electromagnetic energy (electricity) is converted into mechanical energy (rotation) by the fan motor. The fan then turns and air moves through the device. Electromagnetic energy (that same electricity) is also converted into thermal energy in the heating element, and from there the heat is transferred into the air as it passes by.

Chemical energy is turned into heat, light and pressure(sound)
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 e…nergy 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.
uhmm... ELECTRICAL ENERGY- MECHANICAL ENERGY- SOUND ENERGY-HEAT ENERGY :)
Chemical to electric
electrical energy to mechanical energy!
chemical - electrical - light - heat
The primary one is the conversion of the chemical energy in the fuel into thermal energy, which is heat energy. This is converted into mechanical energy by the jet engines, an…d this delivers thrust that forces the plane forward through the air. Then it's all mechanical energy conversions to provide lift and move the plane forward.

A television receiver uses electrical energy, either from batteries or from the electrical outlet it's plugged into, and converts that energy into a tiny bit of light energy, …a moderate amount of sound energy, and a considerable amount of heat energy.
electrical energy to mechanical energy
It transform electricity into thermal energy by the resistance load.
In the speaker, electrical energy is transformed into heat and motion of the diaphragm, which, in turn creates sound waves - another energy transformation. In the pick-up/mi…crophone sound waves are converted to motion in the pickup and then transformed into electrical pulses. There is also some small amount of energy transformed into heat there as well.
In a TV electrical energy is converted primarily into sound and light energies but also heat as a by product of the first two transformations.
Electrical - Sound energy? It used the electrical energy to amplify the radio signal. - that is an electromagnetic wave.
