A refrigerator is like a box that keeps your food cool and fresh for longer.
Imagine you have a basket of strawberries. If you leave them on the kitchen counter, they get warm and squishy after a while. But if you put them inside the refrigerator, they stay nice and chilly, just like when you put your hands in cold water from the tap.
How It Works
The refrigerator has a special engine inside that moves heat out of its insides and sends it to the back, where it warms up the kitchen slightly. This is like having a tiny freezer friend working hard to keep things cool.
When you open the door, warm air from the room comes in, and the refrigerator works a little harder to cool everything down again, just like when you take your sweater off on a chilly day, and the room feels warmer for a moment.
Examples
- A refrigerator keeps food cold so it doesn't spoil quickly.
