Energy transfer in a refrigerator is pretty cool (no joke)! Here’s how it works, step by step:

1. How It Works: The fridge uses a special process called the refrigeration cycle. This process takes heat from inside the fridge and moves it outside.

2. Main Parts: There are four important parts in a refrigerator: the compressor, condenser, expansion valve, and evaporator.

3. Getting Rid of Heat:

   • Inside the evaporator, a fluid called refrigerant absorbs the heat from your food. This cools down the food.
   • When the refrigerant absorbs heat, it turns into a gas.

4. Making It Hot:

   • The compressor presses this gas, which makes it hotter.

5. Releasing Heat:

   • The hot gas goes to the condenser coils on the outside of the fridge. Here, it lets out heat and changes back into a liquid.

6. Keep It Going:

   • This process keeps going, making sure your food stays nice and cool!

This shows how energy moves around in our everyday lives, like with refrigerators!
