A kettle is a kitchen appliance used for boiling water. It typically consists of a container with a spout and a lid, often made from materials like stainless steel, glass, or plastic. Kettles can be powered by electricity or used on a stovetop. They are commonly used to prepare hot beverages such as tea and coffee. Electric kettles are popular for their speed and convenience, often featuring automatic shut-off functions for safety. Stovetop kettles, on the other hand, require a heat source like a stove to boil water. Both types are essential tools in many households for quick and efficient water heating.
