A refrigerator is a household appliance that keeps food and drinks cold. It works by removing heat from the inside, which helps slow down the growth of bacteria and keeps items fresh for longer. Most refrigerators have a main compartment for storing food and a smaller section called a freezer for ice and frozen items. Refrigerators come in various sizes and styles, including top-freezer, bottom-freezer, and side-by-side models. Many modern refrigerators also have features like water dispensers and ice makers. They are essential in kitchens, making it easy to store groceries and enjoy cold beverages at any time.
