A fridge, also known as a refrigerator, is a household appliance used for storing and preserving food and beverages. It operates by removing heat from the interior of the fridge and releasing it to the outside environment. The cooling process is typically accomplished using a refrigerant, compressor, and condenser. Fridge technology has advanced significantly over the years, with modern fridges equipped with features like adjustable shelves, door alarms, and water dispensers. Some fridges even come with built-in screens and internet connectivity, allowing users to stream music and browse recipes. A well-functioning fridge is essential for food safety and minimizing waste, as it helps to slow down the growth of bacteria and other pathogens in perishable items.
