Types of energy transformation transfer in a Refrigerator
Transcript of Types of energy transformation transfer in a Refrigerator
The energy source is electrical power, which would then produce kinetic energy to work the pumps, which would circulate the refrigerant. This reduces the heat in the fridge, increasing the external heat. The wasted energy of the the fridge would be heat and sound.
How a refrigerator works
The fridge removes heat from the air inside the chamber and uses water to cool it.
The compressor constricts the refrigerant vapor, raising its pressure, and pushes it into the coils on the outside of the refrigerator.
When the hot gas in the coils meets the cooler air temperature of the kitchen, it becomes a liquid. Now in liquid form at high pressure, the refrigerant cools down as it flows into the coils inside the freezer and the fridge.
The refrigerant absorbs the heat inside the fridge, cooling down the air. Last, the refrigerant evaporates to a gas, then flows back to the compressor, where the cycle starts all over.
The law of conservation
The refrigerator follows the law of conservation because the fridge does not create or destroy energy, it only transforms one kind of energy to another or transfers a type of energy to the same kind of energy . For example the fridge transforms electrical energy to mechanical energy (heat energy)
Electrical energy light energy (useful energy)
Chemical energy (useful energy)
Mechanical energy (wasted and kinetic energy)
Thermal energy (wasted and heat energy)
Types of energy transformation in a Refrigerator
sound energy (wasted energy)
